info ANALOG
family is generated like as several mini-synthesizers with individual circuits, onboard VCO oscillators, noise generators, envelope VCA stages and filtered by lowpass filters.
Each percussions have different controls:


pot Bass Drum
tune sets the pitch
decay sets the lenght
attack adds a click at the beginning

pot Snare Drum
tune sets the pitch
tone emphasizes the VCF filter and the total decay
snappy sets the amount of white noise

pot Low tom
pitch sets the tuning
decay sets the relative lenght

pot Mid tom
pitch same as low tom but with different range
decay sets the relative lenght

pot High tom
pitch same as low tom but with different range
decay sets the relative lenght

pot Rim Shot
no controls

pot Handclap
no controls


 

info DIGITAL internal ROM 3 PCM samples coded at 6 bits resolution / 18 kHz frequency- the rest of the audio signal path is pure analog including EG, VCF and VCA.
TECH: PCM shots are stored in a 32 Kb ROM HITACHI HN61256P.


pot Hi-Hat (open)
decay makes a long open sound
tune sets the pitch

pot Hi-Hat (close)
channel-shared with opened hihat circuit
they canno be played at same time

pot Crash
tune sets the pitch of the sample

pot Ride
tune sets the pitch of the sample


 


info SEQUENCER is based on famous 16 step entries or tapping method.
There are 3 main sequencer functions that enhance the pattern groove:
1- ACCENT: makes a specific step louder for a single instruments or all
2- SHUFFLE: swings the beat for a more human rhythms
3- FLAME: adds a syncope on a step. It does not apply to: rimshot, claps, hihats, crash and ride.
MIDI it is possible to trigger the sound percussions directly by Midi, but implementation is rather basic and offers only ON/OFF messages.
