BASTL INSTRUMENTS / 1983

A module made by Bastl Instruments, a ""handmade electronic musical instrument"" brand. A polyphonic MIDI to CV interface with automatic tuning function and diverse voice allocation.

A Polyphonic MIDI-to-CV Interface with Automatic Tuning and Diverse Voice Allocation

The BASTL INSTRUMENTS ""1983"" is a polyphonic MIDI-to-CV interface with creative voice allocation and automatic tuning capabilities.

It features four LISTEN inputs and CV & GATE outputs, analyzing the waveform of connected external oscillators. Simply pressing the TUNE button automatically tunes each oscillator across seven octaves, allowing for instant and accurate response to MIDI notes. Furthermore, the μTune function allows for fine-tuning, supporting custom tunings (such as just intonation) beyond equal temperament (A=440Hz).

The four CV/GATE outputs can be configured in various layouts (4 voices, 3+1 voices, 2 velocity voices, 4x1 voices, 1 voice, 8 gates, 8 CCs, 4 triggers + velocity, performance quantizer) to suit your needs.

Furthermore, by utilizing the four CV inputs, it can also be used as a creative ""arpeggier/sequencer.""

All settings of the 1983 can be saved as 10 presets.

■AUTOMATIC TUNING
Each channel of the BASTL 1983 can ""LISTEN"" a simple waveform from an external oscillator, and with just one press of the TUNE button, the response of each connected oscillator is tuned to a 7-octave range, allowing it to respond correctly to MIDI notes (e.g., A4 = 440 Hz). It's truly magical!

■QUANTIZER
In QUANTIZER mode, the four CV inputs (QA, QB, QC, QD) can be used as quantizer CV inputs. In this mode, the BASTL 1983 can be used as a 4-channel performance quantizer. The quantizer scale is determined by playing MIDI notes legato, or it can be edited in LEARN mode.

■MICRO TUNING
The default tuning is equal temperament at A=440Hz, but you can set it to a different tuning system using the μTune function. This allows you to custom detune each semitone within an octave. Just intonation and other alternative tuning systems are also available.

■LAYOUTS
The BASTL 1983 has four channels of CV and GATE, and these outputs can be set to various layouts as follows:

• 4x Voice Polyphony
• 3x Voice Polyphony + 1 Voice Monophony
• 2x Mono Voices with Velocity
• 4x Mono Voices
• 8x Gates
• 4x Gates and Velocity
• 8x CC Channels
• 4-Channel Quantizer
