Lately I use my A-170 either on triggers and gates as a poor man’s envelope or to smooth out the output of a sample-and-hold.

I installed Hemisphere on my uo_c and while it is awesome, I noticed that running a Shift Register on the right side slot it had a small but audible latency. I had the Euclidean Drummer running on the left slot, which worked with no problems, as did Shift Register running on the left slot. I suppose the hardware starts to struggle under too much load, but can someone confirm that this is normal behaviour and if the o_c/Hemispheres does it’s calculations sort of from left to right, so should I run any timing-critical stuff on the left slot?

Is there a better thread for these kinds of questions?

An interesting off-label use of the A-115 is to process LFOs. It’s a frequency divider, and with an LFO this presents as an introduction of variations across multiple cycles. This is a great way to get more varied modulation out of a simple LFO if you’re not using it to process audio. I actually picked up my A-115 expressly for this purpose.

As an aside, a oscilloscope is invaluable if you’re new to modular. There is so much that makes more sense when it’s made visible. I bought a Mordax Data as my 5th or 6th module and it was incredibly helpful in my learning process. There are a few Euro-format scopes, and old external scopes can be had cheaply if you hunt for them. You can also find software ones, but your audio inputs need to be DC-coupled for that to work with modulation. This is a good starting list of interfaces that work this way: https://www.expert-sleepers.co.uk/siwacompatibility.html

I follow. Thanks so much – gonna play around with some of this immediately

Can you talk a bit more about this related lfos and what the modulation you get out of it? I’ve been interested in the Noise Reap uLoaf because of the basic LFO (as a clock or rhythmic modulation) and then having a second one which can be influenced or related. Could i do something similar to this with an LFO and a clock divider thats more weird than simply clock division?

(edit: I see you were referring to a-115 frequency divider which is a bit different than a clock divider and combines the divisions at the output which would give you a variation of your LFO. still interested in your thoughts if you have any)

Hi I have a weird question for you: I’ve been goofing around with Eurorack for a year and a half or so, and I’ve decided to swap stuff around and hope to end up with my slightly shifted MN Shared System (add LxD and STO, sub Erbeverb for Mimeophon). Has anyone else shifted from an amalgam of modules to a single manufacturer and stayed true? I think having a focused system will make it seem complete and cohesive. It will act as the “West Coast” instrument in my life, scratch the modular itch, and give me a reason to reach for other instruments instead of trying to do everything via eurorack. Instead of planning a big rack, I can consider just getting a Roland polysynth, a Moog mono, etc., to compliment (rather than complete) my modular.

Anyone recommend going this route? Would you do it again?

#2559

This is great feedback! Gives me incentive to not do this as quickly as possible (though I may or may not already have a DPO on the way :woman_facepalming:). I was worried about using Maths for up to three voices, although the idea of figuring out which of the four lpgs in the system rang the longest to save an envelope definitely occurred to me! Guess I’ll develop my MI and MN shared system and swap over if I think I can hang with just Maths/PP/Woggle as my mod sources. Heck I suppose one channel of DPO could make for a powerful bonus modulator!

Planning on making a brief video tonight to demo the A-115, but: I would expect a clock divider to output a different set of events than the input. The frequency divider (or at least the A-115) mixes all of its derived frequencies with the source, so you would never get outright replacement. It also is very happy to divide an oscillation that is not a square, whereas I would expect a clock divider to output a series of squares or triggers.

Ok, my understanding of how this worked was nearly completely incorrect! It’s been a while. But it still can be utilized as an odd sequence generator.

What the (or, my) A-115 appears to do (please correct me if I’m wrong here anyone) is, each time the input signal is at or below zero V, it will generate a negative voltage, and when the signal is above zero V, it does not. So, it essentially generates a pulse wave, with the depth dependent on how high you turn a given knob.

The original does this every zero crossing. The f/2 knob does it every 2, the f/4 every 4, etc, down to the f/16.

Additionally, all these voltage changes are summed. Because all the generated voltages are negative, this means the generated “sequence” will always be downwards. It also means you get interesting downward stepping patterns that are transposed as different divisions play off against each other.

I made a crude video of it. You do need to start your oscillator quite high to get it all in range, or else you can offset it.

Have you tried morphagene as a sudo pitch shifted delay?
A setting in firmware to always record live input instead of SOS mix does that. I found it to be so much more controllable and not a wash of bubbling something all the time :slight_smile:

#2566

Do you recall what setting that was?

In my first foray into eurorack I had a mixed manufacturer system, but I often felt paralyzed by the amount of choice - “oh, I could save a few hp if I get X instead of Y and then I could add Z but what about A plus B?” etc, etc. Still, the modulation powerhouse I arrived at (Quadra + Ex., Batumi, Blinds) would not have been possible with a single manufacturer system. I used MIDI sequencing and used interlocking modulation between multiple voices.

I currently have an all Make Noise Shared System and overall I’m very satisfied. I think it sounds amazing and really find that the modules work cohesively together (as one could imagine). I appreciate the no screens ethos. As someone whose life is somewhat ordered I do appreciate the chaos embedded in these modules (not unique to MN of course). Also, not the most important thing I do like the unified a e s t h e t i c s.

To echo @nutritionalzero I really miss having bipolar LFOs in my system (I could use one side of DPO, but it is my only oscillator currently). I underutilize Pressure Points. I grown to love Rene (v1), but it is not as ideal for complex multi-part sequencing (I can’t comment on v2).

Having an issue with Pams envelopes into veils. I was working on a patch last night in which I was using Pams to send two envelopes to separate veils channels to create a “hi hat” (white noise) as well as a kick (signal from tides 2). No matter what I did, I got a very audible click every time the envelope opened the vca. I tried attenuating the envelope cv, attenuating the audio signal, etc. and nothing seemed to work. I solved the problem by using stages, but I can still get a little bit of the click if the envelope is short enough. Anyone experience this?

Anybody here have experience with both the Intellijel Polaris and Doepfer A-106-6? I want to get one of these at some point in the near future, and I’ve always leaned toward the 106-6 because I love the design of it with 8 simultaneous outputs. There are so few sound demos of it out there though, and from what’s available the Polaris sounds better to me. I really don’t like its design though–switching through its filter modes seems tedious in comparison to the simpler 106-6 layout.

hope this helps
