A tactile reel to reel tape studio to play back, manipulate, remix and record your own samples, for both iPads and iPhones.

• Up to 15 individual reel to reel tape players where you can start, stop, nudge, wind and rewind the tape by touching the spools.
• Change playback speed, playback direction, and make a tape loop of a segment of a sound with the start point and loop length knobs.
• Multi-mode lowpass/highpass filter like on a DJ mixer.
• Up to +12db of gain with accurate analogue tape distortion.
• Mixer with 3 FX ends per channel and an insert on the master. You can use either the built-in Reverb, Delay and Distortion, or any AUv3 plugin.
• Record performances either on the master bus or multitrack record each channel of the mixer.
• Modulation page with up to 24 LFOs with controls for waveform, rate, phase, offset, curve and smoothing. Routable to any parameter, similar to a modular synth.
• Motion recording of the parameters for the tape players, the mixer and the LFOs.
• Flexible audio routing for multi channel output.
• Performance mode for older hardware.
• MIDI control and mapping.
• Fine tune reel sensitivity, start/stop speed, and 11 parameters of the tape emulation (such as drive, tone, compression, loss, hiss, etc).
• Basic (optional) tempo sync for files with BPM information in the meta data or in the filename, such as LOOP_128.wav.
