What are free updates?

Every one-time edition gets every update after it, free. The 7.0.0 slot machine, Jackpot and Expansion cost owners nothing — no edition ever stops working.

What do the plans add?

Each plan lifts more of the free allowances and opens more of the app — the table below lists exactly what each one includes. Upgrade any time and pay only the difference; a downgrade waits for your next billing date.

Frequently asked questions

Find all the answers below.

Which edition should I start with?
Start free — it is the whole app and the plug-in with a daily allowance, so you can check it works with your synth first. If you'll use it every day, pick the plan that lifts the limits you hit — Pro lifts every one. The compare table shows what each plan includes.
Is the Randomizer Plugin included with the Desktop Suite?
The desktop app and the Randomizer Plug-in are separate editions; get both with Desktop + Plugin. A plan covers the programs the compare table's "Works in" row names.
Can I change my plan?
Yes, from Account → Subscription. An upgrade starts straight away and you pay only the difference for the rest of your billing period; a downgrade takes effect on your next billing date, so you keep what you paid for until then.
What counts as one randomization on the free plan?
One roll — one press of Randomize or Generate that sends a new patch to your synth. Editing parameters afterwards is unlimited and free. The counter resets at midnight UTC.
Will it damage or overwrite my synth's patches?
No. Rolls are written to the temporary patch area, which is what your synth loads a sound into when you select it. Nothing is committed to memory unless you press Save on the unit yourself.
Which browsers does the web randomizer work in?
Chrome, Edge, Brave and Opera on desktop. It needs the Web MIDI API with SysEx permission, which Safari does not support — so iPhone, iPad and Safari on Mac can't run it. The desktop app has no such limitation.
Do I need the desktop app to use the browser version?
No. The browser version is standalone — connect your synth by USB or a MIDI interface, allow MIDI access when prompted, and roll. The desktop app adds the auto-sampler and the format hub, which need local file access.
My synth isn't listed. Will you add it?
More synths will be added in future updates.
What payment methods do you accept?
Card, Apple Pay and Google Pay through Stripe, or PayPal.
Refunds?
The free plan exists so you can confirm it works with your exact hardware before paying. All sales are final.
