[[File:Analog Synthesizer at SudoRoom.jpg|frameless|right]]
We have an analog modular synthesizer at Sudo Room. We would show a picture, but one of the stipulations of us having it is "no pictures online" - it's better experienced in person anyway!

See also: [[Synthesis]], which records sessions on this modular synth!

== How to use it ==
# Zero out (move to the bottom) all volume sliders
# Turn on the power strip under the synth table
# Plug and play

''We are working on building quick start and "how to" guides that include videos and cartoons on using the synthesizer.'' 

=== Manual ===
There is a printed manual of the synthesizer.

Judytuna:

A Raspberry Pi that records live [[Modular Synthesizer]] sessions.

== what is synthesis ==
* synthesis is a raspberry pi with a [https://blokas.io/pisound/ pisound hat (shield)] for recording the synthesizer station at all times
* [https://www.reddit.com/r/raspberry_pi/comments/qk7glv/my_3rd_pi_build_pi4_8gb_with_pisound_this_one_is/ something someone made with their pisound hat]
* message Jake for access
* please note it's presently a Pi 4B but will be switched out for a 3 because we're already having to run 32bit Debian, because the piSound software is only for 32 bit

=== Maintenance Log ===

* Wed 3/18/26: firmware update (to 1.14 from 3/6/26) by [[User:Judytuna]]. Climbed up the ladder with computer, existing cable kept failing the flash between 2% and 80% done (failed to receive serial communication), plugged in new cable, worked. Note: to put it into flash mode, use a small screwdriver to hold down the top button, unplug to turn it off (it has no battery?), and plug in to turn it on, then release the top button.
* some Wednesday in January 2026: donation & installation by C.S. (Firemware version was at 1.11 from Nov '25)
