Tod Kurt (todbot)Working on another <a href="https://mastodon.social/tags/synthDIY" class="mention hashtag" rel="nofollow noopener" target="_blank">#synthDIY</a> idea. Sort of a scaling up of my “pico_test_synth”. Code first in CircuitPython then maybe Mozzi Arduino

craque is icumen in 🏳️‍🌈I previously wired up the remainder of the dronebox (part of the internals seen here) but hit some complexities: 1. The sustain / compression pedal (top) has a very high gain and there is some resonant feedback in this box already, it might be too much and unnecessary, 2. The broken delay (bottom) I hoped only needed new pots remains broken.Soooo I am doing some light troubleshooting today and figuring out where to go next. If I cannot figure out the delay (which i bought modded), it might be a dud. The sustain I may replace with something else entirely, too.Bypass switches are not included right now, because of the internal modular design. But I am beginning to see situations I would appreciate having a bypass. So thinking how that can be implemented.<a href="https://c.im/tags/SynthDIY" class="mention hashtag" rel="nofollow noopener" target="_blank">#SynthDIY</a> <a href="https://c.im/tags/craque" class="mention hashtag" rel="nofollow noopener" target="_blank">#craque</a>

gndA lot of devices I make unfortunately never see the light of day. This is a story of one such device.FilterVerb is a combination of a resonant low-pass filter and a reverb.

craque is icumen in 🏳️‍🌈Newly rearranged modules for a sequencer + synth voice thing. Nothing new here, just cleared out space in this rack case for another row and built it with modules I own.And in case you're wondering, yes I did this for the track I'm working on. :)This is why I love modular fundamentals and synthdiy - need an instrument? Build one! You cannot do that with a lot of the boutique stuff these days... your "sound" is someone else's.<a href="https://c.im/tags/craque" class="mention hashtag" rel="nofollow noopener" target="_blank">#craque</a> <a href="https://c.im/tags/modularsynth" class="mention hashtag" rel="nofollow noopener" target="_blank">#modularsynth</a> <a href="https://c.im/tags/eurorackmodular" class="mention hashtag" rel="nofollow noopener" target="_blank">#eurorackmodular</a> <a href="https://c.im/tags/synthdiy" class="mention hashtag" rel="nofollow noopener" target="_blank">#synthdiy</a>

pedro 🍉We're getting there. The encoder still jumps back and forth occasionally, and one of tne of the buttons seems to work only 50% of the time.

craque is icumen in 🏳️‍🌈I made an LED fixture for an antique dome component so that the four LED outputs of the pedals can drive it in unison. It works!

Joshua A.C. NewmanI already had to solder in two jumpers to power the multiplexer. It looks like an automatic cleanup took out those traces and I didn’t notice.Maybe the multiplexer address traces got lost at the same time? <a href="https://xeno.glyphpress.com/tags/ObliquePalette" class="mention hashtag" rel="nofollow noopener" target="_blank">#ObliquePalette</a> <a href="https://xeno.glyphpress.com/tags/modularsynth" class="mention hashtag" rel="nofollow noopener" target="_blank">#modularsynth</a> <a href="https://xeno.glyphpress.com/tags/plugdata" class="mention hashtag" rel="nofollow noopener" target="_blank">#plugdata</a> <a href="https://xeno.glyphpress.com/tags/synthdiy" class="mention hashtag" rel="nofollow noopener" target="_blank">#synthdiy</a> <a href="https://xeno.glyphpress.com/tags/eurorack" class="mention hashtag" rel="nofollow noopener" target="_blank">#eurorack</a> <a href="https://xeno.glyphpress.com/tags/experimentalart" class="mention hashtag" rel="nofollow noopener" target="_blank">#experimentalart</a> <a href="https://xeno.glyphpress.com/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#robotics</a>

Joshua A.C.

Some of this could be a firmware issue, which is easy enough to address.
