March 19, 2026April 29, 2026robinv

Luna is a Lunetta-based synthesizer machine from Neutral Labs that can be bought in kit form. It’s not the easiest of builds or the most detailed of instructions but hopefully my build will help you tackle your own.

Shakmat Modular Ballista Blast Synth Voice Review

March 16, 2026April 29, 2026robinv

Ballista Blast is a hybrid synth voice with classic waveforms, wavetables and some funky FM with multiple algorithms. It has a great filter, useful envelope and lots of CV for modulation.

ADDAC Percussion VCA Review

March 10, 2026April 29, 2026robinv

This perky little VCA/Envelope combo has found itself to be very useful in my rack. It’s a VCA with a Decay envelope built in that you can also feed out to a filtercutoff which saves you a bunch of modules.

Sequential Fourm Review

February 26, 2026March 3, 2026robinv

Does this compact 4-voice analogue synth have what it takes to be a serious synth? The Fourm is neat, capable, sounds like a Sequential synth and has an elegant simplicity that really appeals to me.

Arturia KeyStep 37 Mk2 Review

February 26, 2026March 3, 2026robinv

My favourite all time MIDI and CV controller keyboard got an update. It’s taken onboard everything from the KeyStep Mk2 and sprinkled in some deeper levels of hands-on control.
