Bastl Instruments 1999 expands the Neo Trinity Eurorack module with TRS-MIDI and USB-C, providing bidirectional CV integration.
MIDI expansion for Neo Trinity
The Bastl Instruments 1999 has been introduced as a MIDI expander for the Neo Trinity Eurorack module. This hardware links the modulation module to grooveboxes, controllers, or DAWs via TRS-MIDI and USB. Combined with firmware 2.0, Neo Trinity operates as a MIDI-to-CV and CV-to-MIDI interface capable of recording sequences.
Hardware and connectivity
The module features a width of 2 HP and a depth of 24 mm. It connects directly to Neo Trinity via rear pin headers, eliminating the need for patch cables. It is equipped with a TRS-MIDI input and output (Type A) alongside a USB-C port. A dedicated toggle switches between DEVICE and HOST modes.
- Bus power delivery in USB host mode at up to 5 V / 0.75 A
- Forced host mode without bus power to prevent power supply interference
- Automatic clock source detection with selection between TRS-MIDI and USB-MIDI
- Transmission of internal or analog clock as MIDI clock including start and stop
Control and signal workflow
Channel pairs A/B, C/D, and E/F operate as CV/gate pairs assigned to MIDI channels 1 through 3, responding to notes, pitch bend, and sustain via CC64. Parameters can be automated using MIDI CC. Real-time recording of CV/gate sequences is supported via MIDI, while channels E and F can also record from analog CV inputs. When linking multiple Neo Trinity units, MIDI channels are assigned automatically based on position. Only one 1999 module is permitted per chain.
