Create tonal percussion in Logic Pro Ultrabeat
Tonal percussion sounds such as toms or congas are relatively easy to emulate
electronically with sine or triangular wave oscillators. The Ultrabeat phase oscillator offers
you a broad spectrum of suitable basic sounds to start with. Control the pitch of the
oscillators with envelopes, and use the programming techniques discussed in the kick and
snare drum sections to alter tonality. You should find it easy to create a broad range of
toms and similar sounds. See Create kick drums in Logic Pro Ultrabeat and Create snare
drums in Logic Pro Ultrabeat.
Use oscillator 2 model mode to create tonal percussion sounds
• In Logic Pro, turn on oscillator 2 Model mode, then familiarize yourself with the effect
of each parameter. You should find it is quite easy to create your own tonal percussion
sounds, ranging from toms, to small tabla drums, to glass bowls.
• Note pitches A1 to B0 in the Tutorial Kit contain typical 808 toms. Analyze these
sounds and modify them as you see fit.
• Note pitches C2 and C#2 in the Tutorial Kit contain tabla and glass sounds that
combine both Osc2 Model and FM. They are also good examples of the complex use
of velocity as a modulation source.
Create hi-hats or cymbals in Logic Pro Ultrabeat
Electronic hi-hat sounds are easy to create in Ultrabeat.
Create a hi-hat in Ultrabeat
1. In Logic Pro, load the Standard Tutorial sound.
2. Turn off oscillator1 and turn on the noise generator.
3. In the noise generator, make sure the Cutoff parameter is modulated by Env1, the
modulation is negative, and the position of the Mod slider is below that of the base
parameter value.
4. Use rather short decay values for Env1 and Env4.
5. Set the attack time of Env4 to a value of 0. The attack time of Env1 should also be
rather short, but not equal to 0.
Note: You’ll find a similarly constructed sound listed as “hihat 1” at a pitch of F2 in the
Tutorial Kit. Also analyze the hi-hat sound “hihat 2” at pitch F#2.
