Great Potential, Bad Stock Sounds

This is the most full-featured synthesizer available on the iPad at this time. It's range of sound supersedes the miniSynth and the built in sythesizers of Aurora Sound Studio and Bleep Pad, assuming you get the upgrade so you can edit your own sounds. The sound itself is not as warm as the miniSynth or as rich as Bleep Pad, but there are more parameters to modify, giving a greater range of possible sounds. For example, you can switch the filter from LP to HP. You can modulate 6 parameters at once with the mod wheel. You can modulate the pulse width of both oscillators for all waveforms. It has all the parameters you need to make really bizarre noises.

It's best actually for creating really strange noises.

The built-in sounds, in general, are pretty bad. You really have to get your hands dirty to get value out of this, but if you like doing that, you will like it.

Good synth and it's Free!

I gave it 4 stars ONLY because I also own Retronyms Tabletop which I would give 5 stars--I think if I were to purchase the Patch Editor for a mere $0.99, it would be worthy of 5. As a sound designer/musician I create all my own sounds so I don't use pre-made patches...however you can add delay, delay filter and distortion in the free version and they all sound good. The factory patches are also good, but for serious work, I recommend Tabletop by this same company.

No ADSR with the sampler

it's 2013 and this app still doesn't have ADSR when your playing in Sampler mode... if this was added i could actually use this synth. Below is my previous review, and as you can see things haven't changed.

I've had this app for a while now, and only purchased it for the sampler section. I contacted the developer about adding an ADSR section to the sampler, but all they seem to care about is adding more in app purchases, one of which I bought, "the patch editor", but still........ No simple ADSR...... Something every other synth, or sampler would have......... Save your money and buy something else.
