Motas-6 analog monosynth

Hey everyone, I’ve been a lurker here for a while but never posted until now… I’ve been an owner of this synth for a while and I thought it suited the community here very well.

Motas-6

I guess I’ll mainly skim through the features as the website above does a better job of detailing it all, I wanted to talk a little about my own experience with it and why I so quickly fell in love with it and feel the need to share / recommend it:

Some highlights:
3 VCO’s
Analog phase modulation
Mixable waveforms
3 Filters (two resonant, one VERY flexible)
37 LFO’s and 37 EG’s!
Vector morphing on an analog synth

There’s a whole bunch more than mentioned above so check it out on the website but the bit I’d really like to focus on is the digital brain behind it all.

Due to there being a lot of processing power in here and clever design, there’s been a ton of features added since it was initially released and since I bought mine back in March, the following ideas I suggested have all been implemented: microtuning, Audio rate LFO’s that track pitch, independent track lengths of the two sequencer lanes and being able to set the response of the envelopes between the extremes of LOG and LIN with 128 steps.

The LFO’s are one of my favourite features as you can create very complex patterns with them that are relevant to the structures within your music due to being able to set them in HZ.

It’s sad to me that this thing has largely gone unnoticed as it’s truly a labour of love of the designer and also it’s truly incredible and has brought me a lot of joy and I’m sure there’s many others out there that this thing would suit perfectly who are unaware of its existence and end up settling for something less suitable to them.

I’ve been making a bunch of demos to try and show off some of what it’s capable of, there’s also demos by the designer available on his website as well as his youtube but I initially found it very difficult to judge before buying so I have some bits on my soundcloud available:

Demoing / promoting is not something that at all comes naturally to me but I hope that this post finds people who’re looking for this kind of thing as it’s awesome!

Thanks for illuminating me/us! It looks great.

That is so shocking that my brain is quite sure you either meant 3 or 7… yeah that link is being clicked!

Edit: wow a very impressive set of features. To the GAS list this goes!

I understand that this is one LFO and EG per parameter, but how is it resolved in terms of UI? like to set depth, speed, LFO and env settings?

I had the same question, downloaded the manual. looks like you turn whatever knob on the left you want to modulate and the screen will display its settings. The controls underneath the screen seem to switch context automatically so that tweaking them sets the modulation for that knob.

The UI is actually very well thought out, the designer didn’t want the synth to be a horrible menu divey experience, all menus are found by selecting the relevant parameter and hitting the left or right button by the main encoder, any setting is no more than like 2 seconds away.

You have an lfo per parameter but you also have 4 global lfo’s which can be accessed on top of that so you can have two lfo’s modulating each paramater, the envelopes are also loop able so they can double up as an extra lfo on top of that.

Setting the lfo speeds is very quick, they have huge range (up to 440hz in their default setting but they can be set to track pitch instead and they can go from around -36 to +36 steps) it generally doesn’t take more than a few seconds to dial in the speed I want and also there’s some very smart GUI features like the copy function which allows you to copy all the modulations from one parameter to another where you can then alter them, you just touch the pot of the parameter you want to copy, hit copy and then touch the pot of the parameter you want to copy it too.

One thing worth noting about the audio rate lfo’s this was a bonus feature he added on my request, they’re very well implemented but due to certain limitations, there’s some aliasing of the lfo’s starting around the 6th octave if I recall correctly but this in itself sounds very cool, analog sound modulated by digital aliasing!

Oh you also have some ridiculous amount of LFO shapes, something like 50 or more and you have an lfo designer where you can create your own lfo shapes which I’ve never seen implemented as deeply as it has been here, this feature came out the other day so I’ve not actually tested it yet but it looks very cool!

Prior to this I’d been considering getting into modular but after buying a semi modular I realised it wouldnt be financially possible for me as I’d always be wanting another vca or env or lfo or whatever, I also didn’t like not being able to save the patches I’d spent ages figuring out, the Motas-6 has fully satisfied me in what I was hoping to get out of modular but it can also interface very nicely with a modular system due to its 4 cv inputs.

If anyone ever has any questions or any particular demos they’d like to hear of this thing, let me know and I’ll what I can do!

thanks for sharing. I really love the sounds you’ve gotten out of it! The “Pi Drone” track sounds like it could be on a boards of canada record. I’d be curious to hear some short percussive sounds with the noise generator and stuff. I also like the screen ui. it has a sort of elektron look to it.

I started poking around the website and got to the history section of the website, https://www.motas-synth.uk/history.html … I see what you mean about labor of love, that the designer has been iteratively working on this mono synth design for 25 years!

Thank you, I’m happy you like them! It’s so difficult to know where to begin showing this thing off as I generally feel like it’s capable of it all, I’m actually going to buy a second one after I sell a few bits and the two of them would honestly have my satisfied as a sort of strange polysynth.

About the BOC reference, this synth seems very good at nailing those kinds of sounds, it has a bit of a dusty / organic character to it that fits very well into those kinds of sounds but it can also do clean and energetic ones very well too! I’ve got some USB noise bleeding from my sequencer currently which shows up more when I do darker sounds but I’ll be sure to demo that side of it too.

I’ve been meaning to do some kind of evolving / percussive sequence on this thing and I’m working on some more demos right now so I’ll get to work on that as soon as I finish recording the bit I’m doing, I’ll try and get it so that it moves through a great range of percussive stuff.

I email the designer (Jon) quite regularly as we’ve been discussing ideas for it quite a bit, he’s a really lovely guy and quite the genius when it comes to this stuff (as you’d imagine after working with it for 25 years) but he also works with stuff that translates well in his day job so he has a ton of relevant experience for this.

I’ll probably dedicate my studio time today to doing demos for this again and then will probably take a break for a while until I get the whole USB noise issue sorted so if anyone else has anything they’d like to hear, feel free to let me know!

Slept on it, revisited today. This still seems super dope. I could use a poly synth but love mono synths. This seems like a good way to have both. I’m not a good keyboard player so 3-note chords is probably all I’ll ever need. And then this thing does a billion other things. Love the drone demos and the paraphonic demo. The filter demo is also really good, it can get really squelchy and expressive. The screeching, overdriven sounds near the end are sweet.

I’m thinking this is pretty high up my wishlist.

It’s the most special thing I own to be honest, I definitely don’t think you’d regret it! I love the way I can get it to interact with my sequencer too…

Got another demo here:

I’ve made a percussive loop thing too which I’ll record now, It’s largely garbage but it does show off some of the percussive timbres that can be had, It’s a mostly generative loop so it’s constantly changing and there’s some worth while sounds that pop out now and then out of the sludge haha…

Will post shortly!

Edit: And here’s the percussion video, like I said not the best but it’s quite an interesting approach to percussion synthesis, you can make various patches that generate unique sounds and then later cut the ones you like out and put them in your sampler.

The Motas-6 is also great for all your typical percussion sounds (kicks, claps, snares, toms and hats! probably one of the best synths for hats!) But to demo this would be quite a bit more time consuming for me to individually synthesise them all.

I’ve got a few more demos here for you, Just waiting on my usb isolator to arrive so I can demo some darker basses without any whine from my sequencer’s usb showing up.


Both of them vary a bit as the recording goes on but can maybe be a bit of a pain to listen to for a long time haha! can be worth skipping through a bit to catch some of the variations… Especially on that second video, it’s kind of split into 3 sections where the modulation intensity deepens and patch changes a bit each time.

Edit: I’ve got another demo here, someone on another forum asked for some filter sweeps so I tried to capture a whole bunch of different settings for some sweeps, I hope people here get as much enjoyment out of them as that one person did :blush:

Jon’s begun posting over at GS forums, he just posted about the latest update to the Motas-6 firmware and I thought I’d share it here:

"New Motas-6 firmware v0113 is now released!

Get it from https://www.motas-synth.uk/downloads.html
Be sure to check out the updated user guide too.
I’ve added full patch editing during vector-morphing and those expanded modulation options (via M1–M4)… and quite a few other features and tweaks (full listing in README.txt file with the firmware).

Also MotasEdit is updated to v1.08, adding PC keyboard control of slider values and recognises latest new Motas-6 LFO waveforms (from previous firmware release)

Find out more at https://www.motas-synth.uk/news.html"

Pretty huge update, have gone from being able to have 2 lfo’s per parameter to 6… pretty insane! Also a feature not mentioned in the summary that’s pretty interesting is the ability to trigger the randomise patch function via a midi message so you could use that now for some pretty interesting generative approaches, I’ve got some ideas for this which I’ll record soon when I get a chance… If anyone has anything else they’d like to hear from the Motas, let me know and I’ll try my best!

I’m beyond pumped to hear that my 2nd Motas is now finished and tested and ready to ship that that I’ll have it some time next week! I opted for the silver one this time as my studio’s already completely mismatched and I’m a sucker for shiny things… and imo it looks really nice!

Can’t wait to begin exploring the potential of two units, Have been reading into the psychoacoustics of stereo sounds which is very interesting, I’m curious as to what I’ll be able to do with Motas-6 in stereo!

Jon also mentioned in the email that he’s going to continue work on the new firmware this weekend and that he should have it ready some time next week… He’s making it so that when a pot is selected (done by touching it) and you turn page lock and value lock on, The entirety of the modulation section will be mapped across the front panel for easy tweaking, Pretty great! Will make it a lot more intuitive to find the ton of sweet spots this thing has :slight_smile:

That’s it for me now in regards to buying new gear… If I want anything more I’m going to have to build it my self! (or maybe I’ll some day down the line I’ll justify a third one :sweat_smile: )

I’ve also got some more recordings of this thing I thought I’d share:

Just thought I’d share the details on the new update for anyone who’s not seen it. I copied and pasted this from Jon over on GS:

"New Motas-6 firmware v0115 is now released!

Be sure to also check out the matching updated user guide v1.26.

This is a pretty big update (at least under the hood…).
I’ve added MIDI CC control of any patch parameter via a 24-slot mapping.
Mapping is saved globally or with patch.

Added rotary knob control of 24-slot mapping when page-lock and value-lock enabled on patch overview page.

Added rotary knob control of all main page-parameters when page-lock and value-lock enabled on parameter page.

Also my second Motas arrived a week ago and I’ve been obsessively programming the two of them in any bit of free time I’ve had. The more I use them, the more I begin to question if I need any other gear than these two as it’s all starting to get less and less use and feels a little pointless to reach for in comparison.

Here’s a few things I uploaded using the two of them:



Hey everyone, been a while since I posted anything as I’ve had a very busy few weeks but I’ve got some stuff recorded from a few weeks back… Nothing that perfectly shows off the Motas (struggling to figure out how to do that as it’s sound potential seems to be pretty much infinite!)

I’ve got a bunch more to share too once I get around to uploading them although I’m running out of space on soundcloud so not sure what to do there…


How are all you other Motas users getting on? I’d love to hear what other people are making with theirs… I can’t help but feel my own musical taste is probably not what most people are into so would love to hear from someone who has a more classic taste in synth sounds would make with this.

I’m still constantly amazed by what the Motas can do, especially now that I have two of them and it’s great to hear that Jon has a lot of interest in exploring features that could be added for use with 2 or more units… It’s kind of funny but I’ve ended up generally using the two Motas in place of what I’d normally use a poly synth for, I generally like very textured pads and the Motas can just do so much more than anything else I have in that way. Wish more people would take a leap of faith with this thing as everyone I know that has, has been blown away by the sound and features.
