Keyboard (digital piano)

Send line audio, or connect the keys as performance data.

The top path is the sound itself. The dashed line is which key you pressed, and that goes straight to the PC. Either way, headphones go to the audio interface output.

A digital piano (keyboard) connects in two ways. Send the sound itself, or send which keys you pressed. Either one can be a session. If you are unsure, try sending the sound itself first.

The two paths

Send the sound (this page) … the digital piano’s output goes into the audio interface. Your sound comes back in the headphones as it is, and Feelism listens for the pitch and responds
Send which keys you pressed … a jack on the digital piano labeled MIDI or USB goes to the computer. The steps are in MIDI keyboard. Pitch arrives exactly, and the sound you hear is Feelism’s

Connect by sending the sound

On the back or the side of the digital piano, find the jack labeled LINE OUT (or OUTPUT. If those are missing, PHONES)
Run a cable from there to an input on the audio interface. Even if there are two jacks (left and right), one cable is enough for Feelism (left alone is fine)
Plug the headphones into the audio interface’s output. If you plug them into the digital piano’s headphone jack, you will not hear the band
Turn the digital piano’s volume up. Forgetting this is the most common cause
When you play, check that the In number at the top of Feelism moves

If you take the signal from PHONES, the digital piano’s volume knob is the size that enters the audio interface. Set it so the signal does not clip.

Hear yourself

With the starting Self-mix on, your keyboard also comes back in the headphones. If it is quiet, raise Return level in Mix. If the delay bothers you, turn Self-mix off and switch to the audio interface’s “hear me at once” feature (often labeled Direct Monitor). Details are in Self-mix and delay.

Two pianos

Left alone, Feelism’s piano and your keyboard do the same job. Decide who plays.

If you are playing the backing too, clear the Piano check in Settings → Band (Feelism’s piano stops)
If you are only soloing, leave it on. Balance the level with Piano in Mix

When you play a chord

Feelism’s pitch tracking expects one note at a time. While you hold a chord, the response is unreliable. To check the response, try a single-note phrase. The path that sends which keys you pressed (MIDI keyboard) stays accurate on chords too.

Skip these

Leaving the headphones plugged into the digital piano, then hunting for Feelism’s sound
Playing through the computer’s speakers while a room mic picks up the keyboard (the band gets into the mic too)
Turning up both Self-mix and the digital piano’s own speaker (you hear yourself twice, with two delays. See You hear yourself twice)
