Michigan Synth Works Introduces LRB-303 Bassline Synth, An Open Source 303


303 Day: Today, Michigan Synth Works has introduced the LRB-303, an open source version of the classic Roland TB-303 Computer Controlled Bassline Synthesizer.

It’s a full-size clone, controlled by the OS-303 Open Source TB-303 Processor. This chip is a drop-in replacement for the u650 processor used in the TB-303, TR-606, and TR-808. It runs an open-source version of the 303 firmware.

There are dozens of 303-inspired synths, including a free software 303 emulations from Roland, Behringer’s inexpensive TD-3, DinSync’s unofficial 303 reissue, and Future Retro’s 777 uber-303. The LRB-303, though, is open, DIY and hackable, making it at platform, as much as a synth.

Michigan Synth Works says that details on the LRB-303 will be available soon, with pricing for a complete build expected to be around $700.

 

Bela Trails Polyphonic Touch Recorder Now Available To Pre-Order


Bela has introduced Trails, a four-channel touch recorder for Eurorack that captures your finger movements and translates them into melody, harmony, rhythm and more.

Trails generates both control voltage and MIDI information, so it can control all kinds of hardware and software instruments. Gestures can be saved into 16 scenes, for easy recall and live performance. These signals can be used for smooth, continuous parameter shaping, or can be quantized for generating melodic, tempo-synced information.

Features:

  • Record gestures of up to 40 seconds across four channels
  • Simultaneously generate melodic, harmonic, rhythmic and control signals
  • Control MIDI-compatible (hard- or software) and Eurorack devices
  • Generate two touch-controlled CV signals (x and y), plus a gate signal, per channel
  • All CV and gate signals can be quantised to generate melodic, tempo synced information
  • Record gestures individually or on multiple channels at a time
  • Dynamically offset the playback of one gesture against another
  • Slew x and y values with the Touch Bar
  • Transform recorded gestures with rotation, pinch and offset
  • Non-destructively record and undo transformations
  • Dynamically control the playback position and loop in-out point of four gestures
  • Touch control of gesture playback speed
  • Interpolate between multiple banks of eight touch faders
  • Store up to 16 scenes
  • Divide and multiply clocks per channel

The Bela Trails is available to pre-order now for $449 USD.
