Customize: • Time signatures: 2/4, 3/4, 4/4 or 5/4. • Number of measures: 4 to 16. • One or two lines of rhythms. • One, two, or three pitches per line. • With or without rests. • Any combination of note/rest values you want: Whole, Half, Quarter, Eighth, Sixteenth, Dotted Half, Dotted Quarter, Dotted Eighth, Triplet Half, Triplet Quarter, and Triplet Eighths. • Exclude grading note durations to better test percussionists or to focus on accuracy alone. • Listen to the rhythm before and after you attempt playing it. • Tempo 30 to 150 bpm. The required accuracy of attacks and sustains changes with the tempo selected, so if you slow down the rhythm, you need to be more accurate. Likewise, faster tempos will give you a bigger 'window' but it'll be going by faster. • On/Off scrolling line of current location. The Grade Book is filterable by name. Grades include the name, date and time the quiz was taken, all relevant settings (note values included, rests, length, etc.), and score (percentage and letter grade).

The MF-102S Ring Modulator is a re-invention of Moog Music’s classic Moogerfooger MF-102 analog effects pedal. The MF-102 Ring Modulator, introduced in 1998, contained three complete modular functions: a Ring Modulator, a voltage-controlled Carrier Oscillator, and a voltage-controlled dual-waveform Low Frequency Oscillator (LFO). Designed by Bob Moog and his engineering team, the MF-102 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-102 Ring Modulator has been meticulously recreated as the MF-102S, capturing not only the spaced-out, retro-futuristic sound of the original, but also the organic way in which the parameters interact to create a musical playing experience. The MF-102S is an AUv3 effects plug-in that requires a compatible host or DAW to function.
