It’s been about seven months since I’ve got the kit sound lab mini-synth and the pcb for the power supply from MFOS ; and finally I’ve been able to finish it. I followed the basic mini-synth schemes and I added a fine tune to each one of the oscillators ( detailed information at sound lab mini-synth plus ) . Well…this is the final result.

I draw the front panel with autoCAD , this is .gif file of the design.

Thanks to Marc for helping me with the wood box , to VCFool for his atvise , and Ray Wilson for all of his work & detail.

Both the sx-150 and the mini theremin belong to the japanese enterprise gakken. They belong to independent kits and each one of them comes with a magazine that exposes the history of the instrument, its principal propulsors, the most relevant artists and recomends the most relevant LP’s… it’s all written in japanese. It’s easy to assemble and it only requires to screw and load it with four batteries, so you can start enjoying it.

To bend the casio SA-5 I based myself on the Reed Ghazala and Casperelectronics schematics to add the folowing features :

. body contacts
. threshold dial and trigger
. feedback adjustment
. glitch randomizer
. pitch shifting
. power crash

Inside the casio SA-5 once I finished solding and adjusting it before assembly

. one push button for loops
. two toggle switches for glitching loops
. two toggle switches for glitches
. pitch potenciometer
. two body contacts ( to drop the pitch )
. 1/4″ output jack
. one toggle switch to connect the speaker and a reset push button

I have solded twenty-five points in a SNES’ PCB, specificaly on the game cartridge connector, and I used the highly_liquid patch to bend the circuit. I have capture a small 2:15 min. video, by using SuperGameBoy adapter and the GBCamera, as an example of some of its glitches.

I have built this analog modular VCF ( voltage controlled filter ) from the PCB and schemes by MFOS ( music from outer space )

these are the filter features :

. state variable VCF 12db/octave with VC resonance
. simultaneous high-pass, low-pass and band pass filter outputs
. log response to control voltage ( 1V/oct tunable )
. sine wave oscillator at full resonance
. power supply range +/- 9V up to +/- 15V
. voltage controlled resonance ( linear control )

this is the MFOS’ pcb with all the components welded-in

gamespeek had use my song “out of memory” to open an close their episode 77 ( march 6 , 2008 ) . They are a weekley videogame podcast from Northwest Washington, who give the latest gaming news, reviews, previews, release dates and more… This is the first time ( that I know of ) someone uses any of my songs in their show, and they made me “band of the week” on their web ( crazy people ! ) . I just wanted to say tanks and good luck on future episodes.

added features:

. three toggle switches for glitches
. one toggle switch and push-button for loops
. one toggle switch of three positions for continuous bleep (two tones)
. one toggle switch for melody’s loop
. pitch potenciometer
. two body contacts ( to drop the pitch )

. three toggle switches of three positions for glitches
. one toggle switch and push-button for loops
. pitch potenciometer
. one toggle switch and potenciometer for tone generator
. two body contacts ( to drop the pitch ) and reset button
