Frequently asked

Do I need an MPE controller?

No. There are three ways to use a Quiver plugin and none of them is lesser.

1. Any MIDI keyboard. Every parameter is a FROM/TO pair, so the FROM values are already a complete static patch. Play any preset on a regular keyboard and it sounds the way it should.

2. Programmed in your DAW. Every major host (Ableton Live 12, Bitwig Studio, Logic Pro, Cubase) supports MPE editing in the piano roll. Draw per-note pressure curves, slide envelopes, per-note bends directly on your clips and Quiver's gestural surface drives them. This is the underrated way in: analog-feeling motion, every note slightly different, without buying any hardware. The kind of life a static synth can't fake.

3. Live on an MPE controller. Osmose, Push 3, Seaboard, LinnStrument, Continuum. Same plugin, played by hand instead of programmed by mouse.

All three drive the same engine. Pick the one that fits how you already work; the others stay there for the day you want them.

What's MPE and why is it the point?

MPE - MIDI Polyphonic Expression - sends pitch, pressure, and timbre independently for every note you hold, instead of one shared value for the whole keyboard. Played on hardware like the Osmose or Push 3, it feels less like programming sound and more like playing it.

Most synths build a sound generator and then add MPE later, as a retrofit on top of a knob-and-mouse engine. Quiver flipped that on its head. Design starts from the per-note gesture (pressure, slide, strike, lift) and works inward toward the DSP. Every audible parameter has a FROM and a TO value, so the engine is the gesture surface; the static patch and the dynamic patch are one design, not two. That design choice is why the same plugin can sound finished on a regular keyboard and still have an entire second life on an MPE controller.

Which OS and DAWs are supported right now?

macOS on Apple Silicon (M1 or newer). Every plugin is tested in Ableton Live 12, Bitwig Studio, and Reaper. Synths are also tested in Logic Pro. Other MPE-aware VST3 / AU hosts on Apple Silicon should work but are not yet covered by our test pass. Windows 10 or later is supported via VST3 (64-bit); Windows builds are new and not yet part of the full test pass, so tell us fast if anything misbehaves. Intel Macs are not yet supported.

What about Logic Pro?

Synths work in Logic as instruments and are part of our test pass. Audio effects cannot receive MPE in Logic because the host doesn't route per-note expression to effect tracks. This is a Logic limitation, not a plugin limitation; we'll lift the warning the day Apple changes it.

How are license keys delivered?

Immediately, by email, after Paddle completes the payment. The .qlicense file is attached and the plugin verifies it offline on first launch - no online check, no phoning home, no per-machine activation cap.

Can I install on more than one machine?

Yes. A single license covers every machine you own - laptop, studio desktop, secondary writing rig. Don't share the key with other people.

Is there a trial?

Yes. Every paid plugin offers a 14-day fully-functional trial. Drop your email on the plugin page, click the confirmation link, and the trial license file lands in your inbox. No card needed, no feature gates while it's active. After 14 days the plugin politely mutes and waits; one click to buy or enter a license. The 14-day money-back policy (see refunds) stacks on top after you buy.

What's your refund policy?

14 days from purchase, no questions. Reply to your Paddle receipt and the refund goes through. EU statutory rights apply on top.

Where do I report a bug?

Email support@quiver.fm with: your OS, your DAW and version, your MPE controller, and a short description of what happened. Screenshots help. Crash reports help more.

System requirements

Operating system

macOS on Apple Silicon (M1 or newer), or Windows 10 or later (VST3, 64-bit). Intel Macs are not yet supported.

DAW

Tested in Ableton Live 12, Bitwig Studio, and Reaper. Synths are also tested in Logic Pro; audio effects can't receive MPE in Logic (see the MPE question above). Other MPE-aware VST3 / AU hosts on Apple Silicon should work but are not yet covered by our test pass.

Controllers

Designed around Osmose, Push 3, Seaboard, LinnStrument, Continuum, and any other controller that speaks the MPE spec. A standard MIDI keyboard loads the plugin and plays it as the FROM-value static patch; the gestural surface activates the day you plug an MPE controller in.

Formats

VST3 and AU on macOS. AAX is planned for a later release.
