Like the straightforward approach, but needs a few features

I think WubSynth has some promise as an affordable, easy-to-use bass synth for dubstep or other styles that use tempo-synced oscillation. I kind of enjoy Synth Drum Pads by this same developer, so I gave this one a try.

The sounds are decent, and like the all-on-one-screen display approach. But despite having AudioBus and IAA capability, I think WubSynth needs work in at least two key areas. First, does the app have no MIDI functionality whatsoever? I plugged in a keyboard and expected it to at least work with CoreMIDI, but no go. Sure enough, neither the description nor the settings options I could find referenced MIDI. While it's fairly easy to control a dubstep bass line with the on-screen keyboard, it still needs CoreMIDI and Virtual MIDI functionality to allow for use with other controllers and sequencers.

Second, I'd like to see the preset functionality beefed up. It advertises "99 save slots", but I find those are hard to use if you can't also give them descriptive names, maybe sort by category, and view in a menu interface.

I did like the quality of some of the sounds, and the bitcrush effect is a nice addition. Tempo sync works and is easy to access, but I'd like to see an indicator on the time slider for the partition being used (for example: Miami synth in Korg Gadget tells you if it is oscillating by 1/4, 1/6, 1/8, 1/16th note, etc.). With those changes, I'd consider increasing my score to a 4 or possibly 5-star review. I do appreciate the low price point and small download file size!

Far more than decent.

Simply put, it does most of those funky dubstep things and simplifies the process of chaining an fm synth with chorus, distortion, bit crush, etc., and puts lfo spped on an easy-to-use slider on primary menu, just waiting to be midi-mapped. its one flaw is only that it doesn't do AU, but it does Interapp audio, so. Accept it for what it is.

Does not work on current iPad OS

Purchased this app some time ago, and I gave the benefit of the doubt author would update it. Apparently not, this app since I bought it has never been able to make a single sound. Still true today, ipad 4th gen, latest iPad OS. Apple or the author should remove this app as to stop defrauding their customers…
