GLT Audio releases the PM-80, a CS-80 MIDI Controller

The GLT Audio PM-80 MIDI control surface features 75 faders in order to replicate the touch and feel of the real vintage Yamaha CS-80 synthesizer while playing its software versions.

For many musicians, owning a CS-80 synthesizer is a dream that’s out of reach - both financially and in terms of required maintenance. While today’s VST replicas sound remarkably close, the true spirit of the CS-80 only comes alive when you have all controls at your fingertips. That’s why GLT Audio created the “Poor Man’s CS-80” — the PM-80, featuring 75 dedicated faders and a ribbon controller, offering an inspiring hands-on experience.

Use cases of the PM-80:
* Map the PM-80 to your favorite CS-80 VST, such as Cherry Audio's GX-80 or Softube's Model 77.
* Use the PM-80 for other VSTs, by adapting it's parameters using magnetic labels.
* Control hardware directly in a DAWless setup, using the MIDI DIN output (even allowing SysEx on customized firmware).
* Connect to your Eurorack: the ribbon controller outputs to CV and Gate.
* As a powerful generic MIDI controller, the PM-80 can even be used for applications like DMX light control and VJing.

Product details:
* 75 high quality silk-smooth 30mm faders by Alps Alpine (all without detent).
* 30 cm ribbon controller.
* 6 high quality waveform toggle switches and 3 slide switches.
* 1 special switch: while pressed you control 75 additional CCs.
* Slim table-top metal enclosure with screen printed metal faceplate and rubber feet.
* We will share the source code, allowing firmware customization by the user.
* Dimensions of the enclosure: 410mm x 205mm x 20mm.
* Designed and assembled in the The Netherlands.

Connectivity:
* Power and MIDI over USB-C
* 3.5mm TRS MIDI-out (Type A)
* 3.5mm TRS CV & gate out (assigned to the ribbon controller)
