@xylf Can you list? You need to put this patch in the root folder of:
https://www.automatonism.com/the-software

Also be sure to install else library.
Help -> Find external (be patient Deken doesn't output statut (like success)

Fix a missing else/ but I hear only pulse...

@cfry What OS? Be sure to run pd in realtime (using the -rt flag). Do you have glitches with the simple Test audio from the menu (without the arduino patch open)? It might be related to your audio buffer.

@jancsika

Nice! Very nice.

@zigmhount My FX are both externals and abstractions, I am not using LV2 or ladspa plugins. Since you have a single core, I don't think you should use multiple instances of pd or [pd~]. I might be wrong.

@zigmhount The fact that this computer is a single core doesn't change much for pd (since it's single-thread process). I am running a similar setup (4 samples poly for a drumkit) using a low-latency setup with fx (delay, reverb, disto). I think everything that you need is doable with pd, but yes, you need some optimization (switch~) and monitor the cpu.

Be sure to start pd in realtime too (pd -rt -jack -channels 2 -mididev 1 -alsamidi)

Good luck

I still think that $600USD is expensive but I'm cheap I don't know about the commercial viability of a groovebox... but I will share 2 interesting products for inspiration.

ELK audio (low latency 1ms custom kernel) - not sure about the boot time - me I don't mind when I need to wait 40sec before making noise... It doesn't say PD on the website, but of course it would be possible. That's a commercial products AFAIK. https://elk.audio/audio-os/

@svanya I recall an object called [pipe] - not sure if it would help. That's a bit strange.

@CrouchingPython There is no error with your patch, but like you probably know already it doesn't produce sound (your patch send midi out to an external connected software or hardware). Media - Test audio and midi is your friend, it will start the DSP and you can test in / out of both audio and midi.

@ddw_music You can have a quick look at pdmtl abstraction:

Look for all musical.* might have something there that would help you a bit?
