I am Become Car (13+14 /Brass) A remaster of a track I made a while back. Unfortunately I can't play this one live, this patch is extremely quiet and needs tons of gain. You can still hear the hum towards the end

A Journey Into Sound x Light at the Museum of Modern Renaissance, Boston, 11/23/25, live set Thanks to @your_fels for hosting, @vjzombie @nxor.bos and @emmalucilleart for the beautiful visuals! And @eardummerman & @ethercodex for sharing this bill! clip1: ROM patch 10>17 at threshold for direction-random major 3rd glisses clip2: Spiral controller A8,9 gated by A16 for the 'choral voice' timbre Full set recording on youtube & more information on how these sounds were made on my website. Thanks for listening! 🐹

Check out this repurposed DX7 keyboard and digital sequencer for the Casio MT240! Most keyboards (both musical and computer) are periodically "scanned" by a cpu. Imagine 64 keys arranged in an 8x8 grid. The cpu sends timed pulses down the columns of the grid, one by one. If you're pressing a key down, the pulse travels down the column -> out the row. The cpu detects this and correlates it to a key. For example, [img 6], if the key "C1" is pressed down, a pulse travels down Column 0 and out Row 0, and the cpu knows "col0, row0 => C1" This circuit bypasses the original MT240 keyscan matrix by sensing the beginning of the column pulse cycle, and injecting timed pulses into the MT240 rows. Using a schmitt trigger and an RC filter, the beginning of the keyscan cycle is detected on column 0's rising edge, triggering a software interrupt on a microcontroller. The uC then injects its own pulses onto the MT240 rows via an NPN/PNP switching network. With careful timing, any keyboard key can be emulated by injecting into the right row at the right point in the MT240 column cycle. The player can input notes via a repurposed DX7 keyboard (with its own uC driven keyscan cycle), and/or by programming notes into a software sequencer. The combination keyboard+sequencer can lead to some very unusual performance modes, which you can hear in the first clip For Cryptwarbler, this is a huge milestone and feels like the beginning of a new phase in the project. It unlocks the ability to play with two dual MT240s, which is something I've been thinking about for a while. I'm very proud of the software & hardware behind this, and very grateful to be able to have a life that supports making art If you're interested in the technical details, you can read more about it on my website (bio)

Excited to share this first look at a controller I've been working on: a uC sequencer/alternative keyboard for the Casio MT240. What you hear is a sweep of all 61 keys as fast as technically possible: the Casio scans 10 column rows corresponding to tritone subdivisions of five octaves at roughly 130uS/col. The other part of the circuit is a Yamaha DX7 keyboard. The uC periodically pulses the rows of the keyboard matrix and detects which keys are pressed thru the columns. Currently the two circuits work separately, but my plan is to combine them like: Dx7 keyboard -> uC -> MT240. This will let me do some ~cool~ things like short-or-fast-as-possible mode, sequencer/player piano mode, vocoder mode (possibly), individual key latching, and the super-end-goal, controlling dual MT240s. Still working out various things, but stay tuned for a more in-depth technical post and some new music from the circuit-bent Casio MT240 🎵 Happy upcoming spring solstice, - Cryptwarbler / Robin / Alex (Idk why I'm writing this like an email...)

Clips from my set at the Boston Metropolitan Waterworks Museum + score. Huge thanks to @noneventseries for inviting me to open for Jan Jelinek, @azevedoaudio for live sound and audio recording, and @miguelg_nzales @jackamadon for video!

"Strange Logic" is out on Bandcamp & cassette tape! Here are a few clips from the album, first one is the last track on the A side. All sounds were synthesized using the circuit-bent Cryptwarbler. You can mail order one from me for $0-20, pwyk. Hope you enjoy :)

Clips from my soundtrack for @exyl_time 's stop-motion "Untitled Dirt Palace Film" (2025) Most sounds were synthesized using the Cryptwarbler and blended with recorded foley. The film also features the legendary northeastern grind band @trophy.hunt The full short film can be found here: /
