iPad Screenshots


iPCM4 is the first iOS application specifically created to use the iPad within modular synthesizer environment. It features a powerful oscillator engine designed to produce complex waveforms that are impossible to produce with any other oscillator module.
iPCM4 can also be used as a polyphonic synthesizer. In this mode, the application can be used as a standalone synthesizer but it can also be used as paraphonic oscillator, bringing huge new sound capabilities to any modular synthesizer setup.
An iPCM4 voice is made of up to four independent oscillators, each of them offering 204 different waveforms, making the application able to provide any kind of sound, from fat and deep bass sounds, to highly complex time varying spectrum sounds. Each voice can be modulated by an envelope generator (one per channel), a pitch-control low frequency oscillator and a amplitude control low frequency oscillator.
The application can be controlled by any iOS compliant MIDI interface. It also supports RTP-MIDI, while it includes a simple keyboard for users who want to work on their sound design while being totally mobile. And of course, all presets created in iPCM4 can be shared with other iPCM4 users using iTunes and Files file exchange.
