Different Drummer is a very unique and new method for creating interesting rhythmic patterns. It is solely aimed at professional musicians who are looking for something new to inspire their creative process. It does have a big price tag for the app market, but after using it for a while I can tell you that it simply goes further than any other drum machine and gives results that I've never achieved before. I've used it for both drum patterns and synth parts, creating patterns that were beyond my expectations and imagination. This may seem too good to be true, but it's easier to appreciate when you understand the concept behind it. The real power of this machine is based on wave shaping using additive synthesis, combining the fundamental frequency with other partials to create a more complex wave shape. This wave shape is further manipulated by an additional set of rest, tie and dynamic waves. The rest wave creates breaks in the main note wave to create the rhythm, while the tie and dynamic waves are used to connect and accent the notes. The resulting wave is then used to control the pitch of each sample, creating incredibly realistic drum patterns as well as completely abstract. Since each sample has it's own set of controlling waves, the possibilities are endless. To make things even more adventurous there are random and morphing controls which can be customised or you can just roll the dice to create something new and unexpected. While the primary use of this app is to control drum samples within the app, it also can control other MIDI capable apps or hardware. Each drum track has a corresponding MIDI channel so you can run multiple synths or drum machines, but you can also send it all using one MIDI channel.There is also an option to send all the MIDI tracks to one designated output channel, as well as a choice between audio output, MIDI or both. You can also create MIDI files to use in other programs which are easily emailed from the app. Finally there is a sequencer which combines amounts of wave sets into sections to create complete songs with ease. While there are some missing features in this version like live recording, audio copy/paste, Dropbox and sample import, they have already been implemented ready for the next big update. I can say that this app really is an experience worth having, with creative possibilities you won't find anywhere else. It is rare these days to find a relatively simple concept that creates such complex results in such a short space of time. This app might have a very select market but it is getting the sales and the only complaints seem to be coming from people who don't have the app. Without a doubt ... this is a killer App!
