- Page 2 Synthino Mode 1 Synthino has 3 modes, and mode 1 is default. Use the controls to effect the notes played on the attached MIDI keyboard. The top row of knobs is envelope control. The low frequency oscillator (LFO) has FREQ and DEPTH control.
- Page 3 Synthino Mode 2 To change modes hold down button 1 while powering on the device. You will hear a number of beeps that indicates the current mode. While holding the button, turn the lower left pot (LFO FREQ) to change modes.
- Page 4 Synthino Mode 3 Mode 3 has different controls. It allows you to change the waveform used by the LFO. This lets you produce some very interesting oscillations!
- Page 5 Synthino Fine Tuning Procedure The pitch of the Synthino can be fine-tuned to match your other instruments. When powering on the device, hold down the rightmost button. You will hear two beeps, then the Synthino will play an A4 note (A above middle C, 440Hz). Turn the PITCH knob until the note is tuned to your liking and release the button.
