Posted by in equipment, mods & repairs, News, Studio

Modded this little Roland TR-909 together with Claudio of discrete-audio-solutions. All mods are switchable to „stock“ sound (except clap noise).

Mods:

-BD-Tune, BD-Overdrive, BD-Decay Range Extension Switch

-Clap Noise Volume

-Rimshot Pitch variations switch

-Hihat Tune

Also exchanged the eprom to the latest firmware (V4) with stable MIDI timing. Thanks to curetronic for the steady desoldering-hand:)
