There are a few ways to get samples into tardigrain other than using the microphone and recording it live. Deleting the current sample will reveal the built in file browser. From the file browser you can import WAV, AIFF and AIFC files. You can also load samples by drag'n drop from the iOS files app. The third way, also from the iOS files app, is by using share "open with", but please note that this last method only works in stand-alone mode.
All audio parameters can be modulated by MIDI, AUv3 and the built in keyboard. The range bar allows for modulation of only a smaller range of the selected audio parameter. Setting the start position above the end position reverses the modulation.
Make sure to set MIDI channel to omni beacause mpe works by assigning each note a separate midi channel. The seaboard maps horizontal movements to pitchbend, vertical movements to brightness and touch force to pressure. These options are now available to set in the modulation view.
The note trigger function is a way to retrigger playing notes in a rhythmical pattern defined by a 16 step sequencer. Each step has settings for levels and probability for triggering. All notes can always retrigger as a kind of global envelope or individual notes can retrigger to create arpeggios.
4 LFOs are available for modulating a selected set of the synth parameters. Even the LFO speed can be modulated by another LFO. To link a parameter to a LFO, double tap the control for that specific parameter.
