Computer Controlled Bass Line (2016)
Overview The After a first digital clone Aira Tb3, Roland launched a new machine with better performance of its own iconic analog Tb-303 in a limited portable edition (works also on battery) called "boutique" with ACB – Analog Circuit Behavior technology at 24 bit / 96 kHz which emulates analog circuits. Of course years have passed and Roland also added some extra features such as digit display , USB, effects more memory and midi.
Oscillator 1 voices monophonic with 2 different waveforms: saw and square.
Sound can be modified using 6 knobs, pretty similar to the original silver machine:
- Tuning: changes the oscillator pitch
- Cutoff freq: amount of filtered VCF (4 poles emulation)
- Resonance: amount of filter resonance
- Env MOd: sets the amount of signal from the EG that reaches the filter cutoff
- Decay: sets the decay time of the Envelope
- Accent: sets the amount of the EG that reaches the VCF resonance.
SEQUENCER original record mode has been preserved: notes are entered with the mini-keyboard, then each note can be set with lenght, portamento, slide and octave transpose (+/-1). A little less tedious than the original with shuffle mode, step edit (display helps!) but no realtime record mode has been implemented, Midi is still available anyway for direct control.
Internal tempo mode with new fine value, but also trigger input clock instead of DYN-sync connections.
EFFECTS bunch of handy digital effects (overdrive, delay,reverb) have been implemented
MEMORY up to 96 patterns and 7 songs that can be saved by Midi or USB
