MFB522 modded drum machine

video upload by Maffez Synthmods

"This is an ode of sorts to the MFB522, IMO one of the best 808 derivations. Small in size big in sound and sporting such great cymbals and hats. I documented the insides a little for folks who want to do modifications or need service info. Check this link for more details and sounds: https://maffez.com/?page_id=4095"

"Got the Syncussion recreation by Michigan Synth Werks recently and could finally go fully in with modifications, something I would have never dared to do with my old Pearl SY-1. On this page here you find a documentation of DIY modifications for this iconic drum synthesiser (including filter resonance, vco hard sync, and oscillator mode switching at audio rates): https://maffez.com/?page_id=3864."

"This is a dry recording of two modifications on the REV 4 - switchable Triangle Wave on OSC A and switchable Bandpass mode for the REV3 filter. Check my other REV 4 demo for single voice outputs. More on this IDY project here: https://maffez.com/?page_id=3556"

Prophet 5 Single Voice Out Mod - Maffez


"This is a demo of my DIY Prophet 5 Rev 4 expansion board which features, besides TRI Wave for VCO A and Bandpass Mode for the 3320 VCF, Single Voice Outputs. These are not your classic panorama mod but dedicated voice outputs with automatic muting (when the tuning routine runs) and main level control."

"These are some demos and a link to instructions for modifying your Prophet 5 Rev 4. What you get is a switchable TRI wave on Oscillator A and a funky bandpass filter option of the REV 3 filter. There's a whole extension board PCB setup at the bottom this page that gives you Single Outputs per Voice (including auto-mute and volume control) too! - https://maffez.com/?page_id=3556

This is a non-commercial DIY project, so tinker at your own risk."
