One project for software and hardware
Give a MIDS track a MIDI destination and channel, then sequence your external synthesizer alongside Spider’s built-in drum machines and instruments. MIDS sends MIDI rather than generating audio.
Performance tools on the same track
Play a keyboard or pads, expand notes into chords, run an arpeggiator, shape velocity and move hardware parameters with assignable CC controls.
Keep the musical result editable
Melodic and drum step sequences belong to the same Arrangement clips as the rest of the song. Web MIDI support and a connected output device are required for hardware playback.
