Just moved 7 posts to Grid ops / integration at @scanner_darkly’s request.

FYI!

I started making a slice sequencer for use with the ER-301. I’m using all the pattern view columns to create a pattern bank of 16 patterns you can program and switch between. Probably gonna add some controls for changing the speed of sample playback and some randomness per step and also the ability to program a pattern by playing into it live.

Love the grid integration! Thank you @scanner_darkly!

Holy smokes – my GAS for the ER-301 just went up exponentially. That looks incredibly fun to play with

[unity2k]

I’ve got most of the parts having a Teletype, a few Telex, the ER-301 - but I need a Grid. I guess your and my costs are about the same!

[kingcons]

Been searching for how to best integrate my ER-301 and Teletype.

This is wonderful and I’m very excited to try it out! Thanks for sharing.

[scanner_darkly]

great scene! (and really well done video - have you considered doing video tutorials?)
good to see all the recent ops being utilized.
added it to the code exchange page.

[emenel]

This is an amazing scene.

I know I sound like a broken record at this point, but I’d love to see stuff like this live in the Github repo for sharing TT scripts. https://github.com/monome-community/teletype-codex

[jasonw22]

I think there are some typos?

#I
# ...
# G.GBX has too few arguments; G.GRPEN should be G.GRP.EN
G.GBX 3 100 1; G.GRPEN 1 0

#6
# ...
# I think PN.A should be P.N A? 
C - P.I P.START; PN.A

[freqout]

thanks for catching those. i fixed them with an edit!

[jasonw22]

oops, one more:

#8 
# Should be B * 7 G.BTNV
B * 7 BTNV

[freqout]

fixed! hopefully that’s everything

[scanner_darkly]

are you retyping it here manually? you can just save to USB stick and upload the file.

I’m trying to write a solid Earthsea style controller for Just Type in Sustain mode to allow variable note length. It’s going ok but far from perfect. Here’s a video of it in action:

Ghost Hunter

It runs into trouble when playing the same button/note twice with different voices and also it doesn’t steal available voices - rather it just goes through them sequentially.

Has anyone made a more successful patch? Seems like a very good use of grid-teletype interaction. I’m anxious of going down the rabbit hole of trying to write a complicated note stealing algorithm!

#1
IF G.BTNV: PN 0 O G.BTNI
L 1 6: SCRIPT 2; Z I

#2
Y - 7 / PN 0 Z 15
X N + * Y 5 % PN 0 Z 15
I G.BTN.V PN 0 Z
PN 1 Z I
IF I: JF.VOX Z X V 8
ELSE: JF.VOX Z X 0

#I
G.BTX 0 1 0 1 1 0 3 1 15 8
JF.MODE 1
O.MIN 1; O.MAX 6; O.WRAP 1
JF.SHIFT V -2

[scanner_darkly]

that looks great! some notes:

in script 1 if you’re using Z to pass a value to script 2 from the loop you should set it before calling the script:
L 1 6: Z I; SCRIPT 2

if you’re using the latest grid beta you can also take advantage of G.BTN.X and G.BTN.Y ops, so the first 2 lines of script 2 could be slightly more readable:

Y - 7 G.BTN.Y PN 0 Z
X N + * Y 5 G.BTN.X PN 0 Z

for voice stealing you want it to grab the first available, starting from 1? or something else?

[ghost]

for voice stealing you want it to grab the first available, starting from 1? or something else?

Yes, something like this, for example, so that if you’re holding down a long note, it won’t be stolen as you’re playing others but instead they will take an available voice. And if there is no available voice then the algorithm should steal the note that voice that was least recently activated. (This is what I find intuitive and how it works on my poly synths at least)

The other issue is that if more than one voice are allocated to the same button you get strange behavoiur, I’m not sure how to tackle this.

Even with these imperfections, using the grid ops to operate just type like this feels really great!

if you’re using Z to pass a value to script 2 from the loop you should set it before calling the script

This makes complete sense, but does it matter? It seems to function fine the other way too

G.BTN.X and G.BTN.Y ops

Amazing! I’d missed these (though I was also quite proud of my mathematical work around!)

[ghost]

So here is a much better version of the script for nice earthsea style polyphonic control of Just Type. To understand the scene, read it backwards (Start with Initial script, then 8->3)
Set Just Friends to SOUND/SUSTAIN.

ooh looking forward to trying this out!

[xeric]

Oh my! This looks and sounds incredible, is that audio straight out of JF, or are there any patch notes here?
It looks like there’s enough empty scripts to do some more things too – maybe sustain pedal input via Walk?!

I can’t wait to play with this
