FAQ

Frequently asked questions

The questions people ask before buying. Anything not here, ask directly.


Buying and licensing

Is this a one-time purchase or a subscription?

A one-time purchase. Pay $19 once and there is nothing further to pay: no subscription, no yearly renewal, and the licence signature you receive does not expire.

How many computers can I use it on?

Three machines per licence. You can see your activations on the account page, and releasing one moves the licence to another machine.

Does it need an internet connection to run?

No. Only the first activation goes online. After that the signature is verified offline, and the plug-in never uses the network.

Can I get a refund?

Refunds are handled case by case. Write to satodeyannsu@gmail.com.

Can I try it for free before buying?

Yes. The older v0.1.3 build is free: create an account and download it, with no trial period. Being an older build, it does not include the current version's newer features. To try it without installing anything, the browser demo on the product page runs the shipping audio engine itself.


Systems and formats

Which operating systems are supported?

Windows 10 or later (64-bit) and macOS 10.13 or later. macOS runs on both Intel and Apple silicon.

Which plug-in formats are available?

VST3 and CLAP on Windows; VST3, AU and CLAP on macOS.

Will it work in my DAW?

Bitwig Studio is the DAW it has been tested in. It should run in any host that loads VST3, AU or CLAP, but nothing other than Bitwig has been verified. If it misbehaves in yours, write to satodeyannsu@gmail.com.

Is there a Linux or AAX version?

No. Windows and macOS are the only supported platforms, and other platforms and formats are undecided.

Windows warns me when I run the installer.

The Windows installer is currently unsigned, so SmartScreen may warn on first run. Choose “More info”, then “Run anyway”.

How many voices of polyphony are there?

Sixteen.


Features and sound design

Can it load my DX7 .syx patches as they are?

Yes. Hand it a .syx and it imports all 32 voices, reading ratios, fixed frequencies, keyboard level scaling, rate scaling, LFO settings and the sensitivity parameters. Each imported voice becomes an ordinary patch you can edit. It is not an emulator, and does not claim to reproduce DX7 audio exactly.

How many operators are there, and are the algorithms fixed?

Eight operators, and no fixed algorithms. Any operator can modulate any other by drawing an arrow, each connection carries its own depth and phase offset, and an operator can feed back into itself.

Can it play wavetables?

Yes. An operator can play a wavetable instead of a sine, and the scan position can be modulated. Serum and Vital format WAV files load directly.

Are envelopes limited to ADSR?

You can draw the envelope itself. Place as many points as you like, set a curve per segment, and choose where sustain and the loop sit. The ADSR knobs are still there if you want them.

Does it support MPE?

Yes. It accepts per-note pitch bend and reads member channels as ±48 semitones. In CLAP it declares the MPE note dialect, so per-note pitch editing such as Bitwig Studio's Micro-Pitch arrives intact.

Does it come with presets?

They are being made now and will ship in the next version. You can start from Init, and save and export the sounds you build. Loading DX7 banks (.syx) is supported as well.

What languages does the interface speak?

Nine: Japanese, English, Chinese (Simplified and Traditional), Korean, German, French, Spanish and Russian. A wheel in the interface switches between them at any time. Support is available in Japanese and English.


How it differs

How is this different from other FM synths?

Four things. Eight operators wired freely with arrows, with no fixed algorithms to work around. Operators that can play wavetables, so FM and wavetable synthesis mix in one instrument. Envelopes drawn as points rather than set with ADSR knobs. And an interface in nine languages, with support in Japanese.

Why $19?

Free FM synths are frustrating and the established ones cost hundreds. This is priced for the gap between them. $19 is the beta campaign price; the regular price is $49.

Is this a DX7 emulator?

No. It loads DX7 banks, but it is not built to reproduce a DX7. It has eight freely wired operators and can play wavetables — a different instrument that happens to read those files.
