AI Stem Generator Plugin

NeuSynth generates new instrument layers from a section of music you choose inside your DAW.

Context is the section of your track NeuSynth uses to guide generation. You can select up to 60 seconds.

One of the alternative groups of generated tracks, you get up to four per Generate. Each set holds one WAV per selected instrument, and the tracks inside a set are designed to work together.

One request can be up to 60 seconds long. 1 Credit = one instrument at one variation, up to 30 seconds. Requests over 30 seconds and up to 60 seconds use 2 credits per instrument per variation. Every Generate returns up to four variations, so one instrument with four variations costs 4 credits at 30 seconds, or 8 credits at 60 seconds. Before generating, you can check the estimated credits for this generation below the Generate button.

Up to 30 seconds counts as one block. Any partial block rounds up, so 31–60 seconds counts as two blocks.

Yes. Every additional 30-second block multiplies the credit cost for the selected variations and instruments.

At up to 30 seconds, it costs 24 Credits. At 31–60 seconds, it costs 48 Credits.

No. Four variations with six instruments still creates 24 WAV files. The files are longer, so each one uses two 30-second credit blocks.

No. Generation Credits apply to the generated outputs, not the selected Context or uploaded Audio References.

It depends on the number of variations, instruments and duration you choose. Each instrument and variation costs 1 Credit for a request up to 30 seconds, or 2 Credits for a request over 30 seconds and up to 60 seconds. With four variations and one instrument, each Generate action costs 4 Credits at up to 30 seconds, or 8 Credits at over 30 seconds and up to 60 seconds. With one instrument and four variations, Starter (150 Credits) provides up to 37 Generate actions at up to 30 seconds, or 18 at over 30 seconds and up to 60 seconds. Creator (400 Credits) provides up to 100 and 50 Generate actions, respectively. You can check the estimated credits for each generation below the Generate button.

Yes. New users receive a one-time allowance of 24 Generation Credits to explore the NeuSynth workflow.

Trial credits are valid for 12 months after they are granted.

No. It is a one-time credit allowance and does not refresh each month.

It depends on the number of variations, instruments and duration. With four variations, one instrument and a duration of up to 30 seconds, 24 Credits provide up to six Generate actions.

Not yet. The MVP works on one selected section at a time.

You can confirm between 1 and 6 output targets per Generate action.

Yes. Add individual WAV tracks or a complete Variation Set.

Instrument Category picks instruments. Audio Reference uses a sound as direction. Text Prompt describes the layer in your own words.

VST3 for macOS is currently available. Windows is coming soon.

NeuSynth currently supports Ableton Live, Cubase, FL Studio, and Fender Studio.

Starter is $4.99/month and includes 150 Generation Credits.

Creator is $9.99/month and includes 400 Generation Credits.

No. Subscription Credits do not roll over. At normal renewal, unused Subscription Credits from the ending subscription period expire, and the new period's credits are granted. When you upgrade or downgrade, the new plan's Subscription Credits are granted immediately. Any unused Subscription Credits from your previous plan remain available until their original expiration date. Changing plans does not immediately remove existing credits or replace the entire balance with the new plan's allowance. After a plan change, credits with different expiration dates may coexist. Each grant expires separately on its own expiration date. Previously granted credits also remain available until their original expiration date if you cancel.

Purchased Top-up Credits are valid for 12 months from the purchase date.

Subscriber Bonus Credits expire 30 days after they're granted.

Yes. Welcome Credits can be used without an active subscription and remain valid for 12 months after they're granted.

Yes. Active Starter and Creator subscribers receive additional Bonus Credits when purchasing a top-up. Users without an active subscription can also purchase top-ups, but do not receive Bonus Credits.

Upgrades and downgrades take effect immediately. You'll be charged the full price of the new plan—not just the price difference—and receive the new plan's Subscription Credits immediately. Any unused Subscription Credits from your previous plan remain available until their original expiration date.

Cancellation takes effect immediately. The subscription fee you have already paid is not refunded. Any unused Subscription Credits already granted to your account remain available until their original expiration date.

No. Previously granted Subscriber Bonus Credits remain available until their original expiration date, 30 days after they were granted. Purchased Top-up Credits also remain available until their original expiration date. Changing or cancelling your plan does not remove these credits or restart their expiration periods.

Yes. Top-ups can be bought at any time, with or without a subscription. Subscribers also receive bonus credits on top of the amount they buy.
