Multi-Sample Instruments

Custom: Use your own sample libraries. Click Custom above, select multiple .wav files — name them after the MIDI note like piano59.wav, piano60.wav or C#4.wav
Synthonico will determine which ones you have and transpose between them if missing. Don't have any? Create your own in Synthonico alter an instrument and record each note one at a time to make your own sample libraries.
Use the Save / Load State controls above to save and reload the current status of the controls in Synthonico to a txt file.
For many of the controls, clicking the number itself and dragging it will change the value more rapidly.

Sequencer Presets

Convert any notes in the sequencer into a ABC files. Click Covert to ABC then click Download ABC. Rename it to something nice.
In order to maintain notes of different length you have to manually edit them in the sequencer.
Use < before or after a note to halve its duration (e.g., a< or <a for eighth note), << for sixteenth.
Use > to lengthen: a> for half note (2 quarters), a>> for three quarters, a>>> for whole note (4 quarters).
Modifiers for chords should go inside the brackets before the first note. (e.g., {<n5 q 3})
Use spaces to separate notes. Use 'z' for a full rest ( z< for half rest).
