MIDI Thru MIDI In 9 volt DC, Center Neg. 300mA min* The M1 is a powerful multi-function modulation machine with six customized, studio-quality programs: Chorus, Phaser, Tremolo, Vibrato, Rotary, and Filter. Each program has a wealth of options to tune, tweak, customize and then save to one of nine onboard presets (128 with MIDI). A sound explorers delight, the M1 features a dedicated lo-fi knob allowing you to mix various lo-fi parameters to every program.
CONTROLS Rate - The Rate knob sets the speed of the main LFO. Set lower for long gentle movement, and higher for wild and fast modulation. Depth - The Depth knob determines the amount of modulation heard by setting the amplitude of the main LFO. Go from no modulation at minimum to seasick, mind-bending effects at higher settings. Tweak - The Tweak knob and switch offer creative control over three different key modulation parameters as well as three “lo-fi” effects.
CONTROLS CONTROLS Tune Switch (Continued) • Tone: Set the switch to the Tone position and use the Tune knob to adjust the overall tone of the effect. Set lower for darker, more muted sounds and higher for brighter, full-frequency tones. • Symmetry (Sym): Set the switch to the Sym position and use the Tune knob to adjust the symmetry of the main LFO shape you have selected on the Tweak knob. Setting the Tune knob at noon will yield traditional LFO shapes corresponding to the selected shape.
LO-FI CONTROLS Lo-Fi - The Lo-Fi knob allows you to adjust the overall amount, or “mix”, of the six lo-fi parameters. Turning this knob up brings in any lo-fi parameters that are engaged while maintaining their relative mix, making it easy to blend in unique combinations of these effects to taste. Setting this knob to minimum turns off all lo-fi parameters no matter their individual levels. Env: Lo-fi Envelope allows you to dynamically open the Tone control based on how hard you play.
PRESETS The pedal includes 128 total presets slots. Good luck using them all! The first 9 presets are accessible from the pedal using the Bank switch and both stomp switches. All 128 are accessible via MIDI Program Change messages, which are outlined in the MIDI section. o To recall a preset: 1. First, select the bank of presets you want to access with the A|B|C switch. The pedal will automatically recall the first (red) preset in that bank. 2.
MIDI The M1 can be controlled via standard MIDI messages. Simply connect your MIDI controller to the M1 MIDI “IN”. Downstream MIDI devices can be connected to the MIDI “THRU” which simply lets all incoming MIDI messages pass through to your other devices. The M1 ships with the MIDI channel set to 1 by default. o To Change the MIDI device channel: 1. Hold down both stomp switches at power-up until the Red preset led starts flashing, then release both switches. 2.
HARMONIC DITIONAL TRA TRI-CHORUS • Phaser - Classic 70s phaser sounds we all know and love, with added features that you wouldn’t expect. Type I is a 2-Stage Phaser that produces a single notch to the classic mild phaser. Type II is a 4-Stage model producing 2 notches for a stronger effect. Type III is a phaser modeled after the unique tuning and LFO shape found in a Uni-Vibe.
• Rotary - Because you can’t fit a Leslie speaker on your pedalboard. Type I aims for that traditional watery sound of a well-oiled Leslie speaker. Type II only spins the horn but still plays the sound out of the drum. Type III only spins the drum but still plays sound from the horn.
