Roland TR-909 tune+decay mods, firmware upgrade
Modded this little Roland TR-909 together with Claudio of discrete-audio-solutions. All mods are switchable to „stock“ sound (except clap noise).
-BD-Tune, BD-Overdrive, BD-Decay Range Extension Switch
-Clap Noise Volume
-Rimshot Pitch variations switch
Also exchanged the eprom to the latest firmware (V4) with stable MIDI timing. Thanks to curetronic for the steady desoldering-hand:)
