POMPA
Draw the pump. A volume shaper that runs at your DAW’s tempo — and shows you what it does.
Windows 10/11, 64 bit. VST3 and Standalone. No macOS, no AAX, no AU.
The free download has every feature, but the effect drops out for 2 seconds every 45 seconds — in your export too — and you cannot save presets of your own yet.
- Price incl. VAT. Seller is Ayhan Doğan (aysound) — see the legal notice for the address, the right of withdrawal and how refunds work. Card payments are processed by Stripe.
- Every update within version 1.x is free. Your licence never expires.
- Support in Turkish, German and English — answer within 2 working days, at info@aysound.com (the POMPA answers are here).
- One key, one paste. No account, no online activation.
try it for as long as you like
There is no seven-day clock. POMPA is a free download and it runs completely: all 16 curves, the curve editor, every factory preset, as many tracks as you want, all six interface languages. No account, no email address, no expiry date, no reminder window.
Two differences, and only two: every 45 seconds the effect steps aside for two seconds, and you cannot save presets of your own — loading them, factory presets included, stays free. That is the whole trial mode. Paste your key and both are gone for good.
We say this out loud because it matters: the dropout is in your bounce as well. POMPA points it out once per session in its own window, and we write it here — so nobody finds out after uploading a master.
what it’s about
A sidechain compressor guesses the shape of your pump from attack, release and ratio. POMPA does not guess: you pick the shape, or you draw it. It runs at your project’s tempo, one cycle per note value, and the beat-locked display puts the kick on the left edge every single time. You see the duck itself, not a wave scrolling past. With pre-dip the level falls before the kick lands — the move that really makes room in a crowded mix.
in detail
- 16 original curves — pump, sub, trim, reverse suction and gate patterns
- Draw your own: drag points, double-click to add, right-click to remove, bend every segment
- Beat-locked display: input and result in one picture, the previous cycle as an afterglow
- Three triggers: DAW sync, a MIDI note, or your real kick on the sidechain input
- 21 rates from 1/32 to 2/1 — straight, dotted and triplet
- Pre-dip up to 50 ms: the duck starts before the beat, latency reported correctly
- Band ducking on the low band or the mid (M/S) only, with band solo to check it
- Depth and mix separately, snap against clicks, phase offset for swing
- Simple view with seven controls; advanced adds the rest without moving anything
- Interface in six languages, 16 factory presets, A/B, undo/redo, scalable window

questions before you buy
I have a Mac. Can I get my money back?
Yes. POMPA is Windows only — VST3 and Standalone, 64 bit. If you bought it for a Mac, write to us: full refund, no questions.
Do I need an account or an internet connection?
No. POMPA checks its key on your own computer and never goes online — not to activate, not to look for updates. It will still run in ten years, with or without us.
On how many computers may I use my key?
On the computers you work on yourself, studio and laptop included. The key is personal: passing it on is what gets a key blocked in a later version.
I lost my key.
It is in the email you got when you bought it — search your inbox for “POMPA”. If that email is gone, write to info@aysound.com from the address you paid with, or with your order number, and we send it again.
Is the free download a cut-down version?
No. It is exactly the same file with exactly the same features — every curve, the editor, every factory preset, as many instances as you like. Two things wait for your key: the 2-second dropout every 45 seconds, and saving presets of your own. Loading presets, factory ones included, is free.
What happens with version 2?
Everything inside 1.x is free for you. A version 2 would be a new product, with a discount for owners of version 1.
Can I use POMPA commercially?
Yes. Releases, client work, streams — all of it. There is no additional licence.

The free download is the complete plugin. Take a week. Or a year.
