Features & Capabilities

It’s not an emulation or simulation of the TB-303 synth. It is an homage to TB-303, and other hardware synths. It’s a complete different beast, but it has the same functionality. It growls and barks with fierce resonance. SquareAcid is a singular squeal, squelch, and bleep machine.

It comes as a stand alone app with Audiobus and Ableton Link. It also comes with an AUv3 audio unit plug-in.

Features:

Audiobus

There are things to like about this, the sequencer is easy to use, and the basic sound. it delivers is phat, but the one big problem is there seems to be no way to separate notes. Use of the decay function only effects filter envelope, every note runs into the next one like it’s one continuous sound. you can erase a step, which will create a hard gap, but when you have a couple notes in a row, there is no way to create separation between them. I would def. use Troublemaker before this.

I had sudden urge for a 303-esque sound, stumbled upon this app and was convinced by the positive reviews. So far I’m quite disappointed. It’s not recognized by my AU host (Zenbeats) despite multiple full scans, I can’t seem to find any way to setup midi, there’s just a generic “midi on” button in the settings. The sequencer is a little clunky to handle (I sometimes have to try 5/6 times to successfully remove a “slide” note) and fairly limited, and since I can’t make it work with my other things so far it’s fairly useless other than pointless fiddling Even the sound itself doesn’t impress me, but hopefully that’s something that can improve as I play more with it. Before buying this I was playing with a browser based 303 clone that was much more satisfying and better sounding. For the price I was hoping for a more “finished” app... competition is fierce.
