Bastl Instruments Trinity x4

via this auction

"Bastl Instruments Trinity, included is SQNCR, DRUM, POLY & MONO FM modules and an unbuilt MIDIbastl mondule.

Trinity is universal musical instrument and original sounding modular groovebox. It can function as any type of digital synthesizer, sequencer, controller, arpeggiator or almost anything that can be programmed into a micro-controller. Trinity is designed to be connected and combined with other Trinities of different functions in a chain, so you can create your own music making environment. It is ready to communicate with the outer world via MIDI and different sync and CV methods using MIDI Bastl. We are musicians passionate of exploring new fields of sonic experience – we already developed 4 different instruments for Trinity which work great together. They are sequencer, drum synthesizer, polyphonic synthesizer and monophonic FM synthesizer.…and there is many more to come!

MONO FM module
experimental monophonic FM synthesizer
8 different sound for each preset
6 presets
1 carrier oscillator with pitch tuned in semitones
3 modulation oscillators with adjustable harmonic multiple of carrier frequency, detune and amount of modulation
8 algorithms of oscillator configuration
3 wavetables for all oscillators (sine, saw, white noise)
LFO with adjustable rate, resolution, amount, destination on different parameters and 8 different shapes
exchange sounds between more Mono FM Synths by SysEx message
MIDI native by side connectors, note, CC support, thru
MIDI connector by connecting MIDI Bastl by the side
POLY module
subtractive or FM synthesis mode
3 voice polyphony
6 different sound for each preset
6 presets
in subtractive mode: oscillator + state variable filter with cutoff and resonance ( LP,HP,BP,notch )
in FM mode: oscillator + modulation oscillator with selectable wavetables
LFO with adjustable rate, resolution, amount, destination on different parameters and 8 different shapes
ADSR with impact on volume and adjustable impact to other parameters
precise setting of oscillator, LFO and ADSR features are accessed by adjusting character knob which goes thru all possible settings of routing and wavetables
exchange sounds between more Poly Synths by SysEx message
4 wavetables (sine, saw, distorted square, noise)
3 note playback by MIDI – velocity sensitive
multi-timbral MIDI mode (lowest octave)
MIDI native by side connectors, note & velocity sensitive, CC support, thru
MIDI connector by connecting MIDI Bastl by the side

DRUM module
5 voice polyphonic drum sample player (6th voice for metronome)
step sequencer
32 steps / pattern
5 storable patterns for each preset
random pattern generation
pattern copy / paste
recording from the buttons
erease single notes or whole pattern
metronome
jump – repeating certain step
tap tempo
auto quantize
6 different drum sounds for each preset
6 presets
mystery shuffle
for each sound you can adjust sample rate, time stretch, cut, distortion, volume and sample to be played
global mode for tweaking all samples at the same time
4 different official drum kits (lo-fi TR909, classic from DRUM 1.0, gameboy, glitch)
drum kits / samples can be changed by converting wave files into .h file included in the source code (by python script included in Mozzi library) and updating the software in the Atmega
MIDI native by side connectors, note & velocity sensitive, CC support, thru
MIDI connector by connecting MIDI Bastl by the side

SQNCR module
controlling 3 different Trinity instruments (polyphonic or monophonic)
sending MIDI notes on 3 channels
32 steps / pattern
4 patterns for each instrument per preset
3 presets
recording from buttons or MIDI
erase single notes or clear whole pattern
adjustable pattern length, groove, tempo
tap tempo
jump function (step repeater)
auto quantize
MIDI clock support, master or slave (by receiving MIDI clock message it turns into slave mode)
MIDI by side connectors – MIDI connector by connecting MIDI Bastl by the side

MIDI Bastl module (Unassembled)
jumpers to select functionality and routing of the MIDI connector (with chain connectors and sync dev. area)
MIDI I/O
Attiny 85 based development area for almost endless sync possibilities (firmware for attiny still in development)
converts MIDI clock to CV clock (4 PQN and 12 PQN) for Korg Volca/Monotribe, Modular, Gameboy Nanoloop/LSDJ (done)
converts MIDI clock to din sync 24 /48
Standalone use: MIDI Bastl has no power jack and is powered via the side connectors from an instrument. For standalone use you need to make power jack adaptor. On the circuit board there are clearly marked spots to which you can solder cable to the power jack."
