While the U.S. is celebrating some madness with turkeys, Pi Synth and the rest of the world are celebrating Doctor Who Day! Here he plays the theme song on a Raspberry Pi Zero. This is an impressive amount of synthesis for the tiny $5 computer. The Pi is even doing the visualization and recording while all of the synthesis is going on!
As always, synthesized live on a Raspberry Pi Zero, featuring 10 simultaneous synths, 3 different synthesis models, audio and graphics captured real-time running on a £4 computer.
It's nice that the software still works - mine has a dreadful tendency to code rot if I look away for a few months. The visualisation is somewhat different since the last time I posted this - the texture that drives the colours is now computed rather than loaded, and as a result it's easier to tweak the visuals, so it all looks cooler and more electro-neon than it did before. The software now runs client/server. Synthesis is within a separate server application, the client is in charge of pushing MIDI into the server, and - unusually - pulling audio back. So the server knows nothing whatsoever about platform MIDI or audio capabilities. Visualisation is also done client-side. So the server does nothing except pull in commands and push out short blocks of synthesized audio.
I got inspired by other people using the Poly iOS app in their improvisations, so I decided to try it myself.
The Poly app generates notes in a defined range, resulting in polyrhythmic patterns. These notes are sent via MIDI to the Volca FM, which itself plays a loop of a few notes. I decided to with the Xylophone FM patch, without extra edits, just knob tweaking. The FM is connected to the Zoom MS-70CDR, which adds the delay and reverb. The output of the Zoom is sent to the Behringer UCA202 USB sound card, which is in turn connected to the iPhone 7 that is used for recording the video and audio.

YouTuber ngarjuna did another interesting modular jam with apps. This one starts off kind of weird, but he builds in a nice groove by the 1 minute mark.
When I saw Expressive E's TOUCHE' earlier this year I thought it looked like an excellent way of extending expressivity, but at €400 it seemed a bit steep for the capability it provides. YouTuber gattobus is doing a pretty good job of convincing me otherwise in this demo jam! He's patched up an analog physical model of a Cello on his Eurorack modular synth, which sounds amazing when played with the TOUCHE'.
I took advantage of the amazing features of Expressive E TOUCHE' to play a physical model recreation of a classic cello built with my eurorack modular synthesizer.
I used Karplus/strong technique: a noise source through an analog BBD delay used as a resonator.
The sound may not be perfect but the sensitivity of this controller make it feel so real. :-)
You can find the patch description at the end of the video.
I hope you like it!
