Prototype Jam! TINRS Fenix IV, mmalex Plinky and Faust on Teensy 4.0

"Here's a little prototype jam, using all the lovely modular gear and hardware we've been testing these last weeks! The granular glockenspiel is made with This is Not Rocket Science's Fenix IV Eurorack compatible system-in-a-box - this is a beta machine but production hardware is actually done! TiNRS’ Stijn and Lauri built in an awesome way to load sample banks into the digital oscillator in wavetable mode, so we were able to use a recording of my childhood glockenspiel as grains in this synth sequence, with beautiful warbles from the onboard delay! TiNRS Fenix' sequencer allows for each of its four channels to have its own rhythm subdivisions and to be transposed via MIDI - this is exactly what's happening here using the Arturia keystep pro. Fenix' extra seq channels are triggering a kick from GHzTomash Callisto teensy arduino DIY drum module, and gating some noise percussion using the Fenix' VCA. The lush swell of reverb at the end is coming from a combination of Fenix built-in verb and using our beta unit mmalex Plinky as an FX processor - DIY kits and the expander will soon be available again from Thonk.

The stereo organ pad is made on a Teensy 4.0 arduino, running an additive synth patch made with Faust DSP and the teensy audio library, controlled via MIDI with the Arturia Keystep Pro and patched into the Eurorack with our own Multiplikand module. It's rhythmically chopped using This is Not Rocket Science's Wobbler complex LFO into Mutable Instruments Streams dual dynamics gate, using the TiNRS Fenix' sequencer to reset the LFO in time with the sequence. The bass is Moogs DIY voice Werkstatt 01, a CV-controlled voice with a ladder filter and that lovely Moog sub.

The beats in the ending come from our circuit bent e-licktronic NAVA TR909 clone, sequenced using the Roland Aria TR-8 drum machine. While the NAVA is an exact copy of the famous TR909 circuits, hacked by us with 34 mods to vastly expand the sonic palette of the instrument, the TR-8 is a digital emulation of the same synth and somewhat shunned for its color scheme. If you look beyond that, it's a very practical and lovely machine.

❤️ Huge thank you to everyone sending us stuff to test and build! This is extremely fun!"
