Dinsync Re-303

Space Cadet Bass liner (2019)

DinSYNC

"The DinSync RE-303 claims to be a REPLICA of famous Roland tb303 not a mere clone , in a affordable DIY project "

Overview 

OVERVIEW The DINSYNC manufacturer, from modular world, took the iconic Tb take the original and recreated the printed circuit board.
The case depends of course on what you are able to do! however some models ready to go are available, most common are of course SILVER like the original or a classy black version. So true first project used original CPU UP650C or alternatively, the Quicksilver CPU. Some times later engineer of well-known Sonic Potions developed and provided his own CPU with enhancements like Midi, better recording mode, random pattern generator , playback directions and a modern memory storage system. Other difficult parts are transistors (2SC2291, 3x 2SC1583, 2SK30A-O, LA4140, 8x 2sc2021R.) and some IC like the famous BA662 VCA chip which controls decay and accent, but it has been cloned also.

Sound

OSCILLATOR  1VCO oscillator with 2 different shapes (sawtooth and square). Sound can be modified using 6 knobs:
- Tuning: changes the VCO oscillator pitch (range: +/-700 cents)
- Cutoff freq: amount of filtered VCF
- Resonance: amount of VCF resonance
- Env MOD: sets the amount of signal from the EG that reaches the VCF cutoff
- Decay: sets the decay time of the Envelope
- Accent: sets the amount of the EG that reaches the VCF resonance.

FILTER: famous resonant and screaming diode Ladder VCF at 4 poles

ENVELOPE decay and accent.

Sequencer and Memory

SEQUENCER like the old one,  notes are entered with the mini-keyboard, then each note can be set with lenght, portamento, slide and octave transpose (+/-1) . You can still use Midi anyway to trigger notes.
SYNC tempo from 40 to 300 BPM or sync to external analog DIN-SYNC or digital MIDI SYNC 

MEMORY  4 groups of 16 patterns
