The Pro Soloist Black Friday deal takes 51% off Cherry Audio's virtual instrument, bringing it to $24 until Dec 1, 2026.
Pro Soloist is a software version of the preset-based monophonic analog synth ARP released in 1972. The DSP design comes from developer Mark Barton.
Cherry Audio says it goes well beyond emulation. The original controls, the 30 factory presets and the underlying architecture are all reproduced, then opened up so everything is programmable.
ARP launched the Soloist in 1970 as the first commercial preset synthesizer, with 18 presets. The 1972 Pro Soloist grew that to 30 and added digital read-only memory chips for steadier tuning.
It also introduced a touch sensor keyboard, what we now call aftertouch. Pressing harder after the note starts could bend pitch, add wow, growl, brilliance and vibrato, or change volume.
The original was monophonic and preset-bound. This version adds several things:
A "last" note option lets a monophonic aftertouch controller simulate polyphonic aftertouch.
The interface has three panels. Performance mode gives you the original paddle presets as MIDI-mappable switches. Edit mode exposes the synthesis parameters. Arp/FX mode holds the arpeggiator and effects.
The maker calls the Resonator Bank the key to the realistic acoustic timbres. It is five parallel bandpass filters with variable frequency and resonance, each modulatable from the Mod Matrix, and each settable to the original frequency curves.
Other parts of the signal path:
Over 400 presets are in the browser, made by sound design veterans, alongside the 30 original paddle presets. Every control has MIDI learn and DAW automation, and the oversampling control is user-adjustable.
It comes as AU, VST, VST3, AAX and standalone on Mac, and as VST, VST3, AAX and standalone on Windows.
Mac needs 10.13 or above, 64-bit, with native Apple Silicon support. Windows needs 7 or above, 64-bit. Cherry Audio recommends a quad-core CPU (3.4 GHz on Mac, or an M1) and 8GB of RAM on both.
Yes. The Pro Soloist Black Friday deal is 51% off Cherry Audio's virtual instrument, which brings it to $24, with the offer running until Dec 1, 2026.
Yes. It ships in VST, VST3, AAX and standalone formats on Windows, and Mac adds AU to that list. It is a virtual instrument based on ARP's 1972 monophonic preset synth, so you load it in your DAW.
It includes all 30 of the original ARP factory presets as paddles, plus over 400 more from sound design veterans, all in one preset browser. Cherry Audio says the original sounds are exactly reproduced.
Cherry Audio made it fully programmable and polyphonic, with 16 voices per layer. It adds split and layer modes, a six-slot mod matrix, an arpeggiator, 12 effects and full MIDI support, none of which the 1972 hardware had.
