Rej is best best mobile DAW developer !!!
and the reason why, let me explain, i bought and tried every mobile DAW for Android phones or iPhone and Auv3 which are 3rd party instruments and fx plugins that can be used in most Daw in the app store for does who didn't know, anyways I thoroughly and deeply try every app and made a full projects in them, but non of that "fancy" and "advance looking" Daws can compare with Caustic 3, first of all Caustic work flow mainly because the rack concept and the sequencer added ready on the rack with each instrument, also the simplicity of editing the notes in the sequecer, to me is the biggest plus of caustic because when inspiration hits, grabbing your ideas and layering them down should always be an easy process, as easy as with Caustic,,
which is the most important thing in music production especially in mobile beat making, !!!!!
also when it comes to editing samples there is no other that gets close to the PcmSynth, first of all sf2 files are samples too, so it should always be a most in a sampler,.Rej thank you for understanding that, anyways the PcmSynth has mostly all the editing tools that you need in a sampler, the volume envelope, the filter with its futures, LFO thats a bonus and great bonus by the way, and everything else on the surface, but also under the hood, we got the Stereo to Mono which is very but very important, save sel. also very valuable option, Remove, Cut, Paste, Crop, mute, Normalize, Amplify, fade in and out, Reverse, FIND ROOT, Pictch/Time, and the ability to edit your sample even more with the Effects options, the only thing missing is the option to setup various slices to sample and be able to set each slice point to a note key and play it instead of chopping slices saving it, import back into a note key,
but thats ok because i do enjoy chopping and saving each chop from samples in the pcmsynth,, anyways its also missing the option to load mp3 !!! other then that the PCMSYNTH is the best mobile sampler and still is the best, and all this are my personal top reasons why i feel Rej is best developer, because he created Caustic, the best mobile app pound for pound.. my final though on what should be Caustic 4 if there ever be a caustic 4, well the same as version 3 but with some options, like an audio track, unlimited tracks well what ever your device can handle, and for the iPhone version the option to add auv3 plugins into the rack in Caustic and thats it !!

and by the way sorry for my English, Spanish is my main language !!
