What’s New

Version 1.5.4

- Fixed: Ableton Link was not working in the network between Ableton Live and Pure Acid on the newest iOS versions;
- AUv3: Midi In Channel settings bug fixed. Previously, audio units always had [Bass: Any, Drums: 10] Midi In channel setting. Now it corresponds to what you set in the standalone's global Midi In Channel settings (Settings menu);
- now you can Paste a bassline (or drums) pattern into a new pattern slot during playback right before jumping to that slot. It is helpful during live playback if you want to create several bassline (or drums) patterns by copying one to another without interrupting the playback. All you have to do is tap the destination pattern slot, and then quickly tap the Paste button right before the cursor jumps to that pattern slot.

The Ultimate Acid Trip

It’s all right here folks. No need to look any further if you want a premium dose of high quality acid app coding. I’ve tried a lot of emulations and also the real deal. This tops it all for the most fun and comprehensive all-in-one self contained experience.

The sound is full and warm with definition and detail. The sequencer is a real treat. The scale modes and variation/shuffle function is excellent. It plays well with other apps and I’m going to try and sequence my TD-3 with Pure Acid in the next day or so.

I can’t believe I didn’t know about this until a couple days ago. Better late to the party than never. My only minor and petty niggle is that you can’t change the custom colors for the main 303 knobs. If that’s the only gripe I have then this app is near perfect. I can’t keep it closed.

Great for Beginners and Veterans

I am a beginner in the iOS music production world. I really got frustrated with many apps, trying to make synths work with certain DAWs, trying to get something started and enjoy myself in the process.
This app delivers exactly what I want! It’s super intuitive and compact. So I find myself learning while I can actually have sort of a live jam session, or even program nice drum patterns with ease.
Now the sound of the Bass in this is App is a certain kind of sound from earlier Acid House Days, or maybe Chemical Brothers come to mind. But there are swing options which make for a whole different vibe if needed.
If you are a beginner, or if you are familiar with iOS music production, either way you should not miss out on this. Tons of fun!!

Impeccable Sound Quality

Honestly one of the best sounding soft synths on iOS alongside Poison. The effects are top notch and really allow you to tame and expand the sound, and most of the muddy low end that you would get on the real deal can more easily be scooped out with tuning up without affecting clarity.

One spot for improvement - having a standalone bassline and mixer in the auv3 would be very handy given I sequence and program drums externally. Currently, the drums and sequencer are just extra clutter and cpu to deal with when hosted even though the kits do sound great. Heck, I would even pay the same just to have that.
