Euro Rack Drum Modules and Trig Sequencer

Percussion modules based on LepLoop V2 Cassa design.

• Cassa: Same as LepLoop v2 Cassa, hard\soft BD generator can go full resonance.
• Cassa CV: Add cv control over frequency and resonance with cv amount.
• Bongo: Same as Cassa one octave higher pitch range, Tom and Bongo like sounds.
• Bongo CV: Add  cv control over frequency and resonance with cv amount.
• Legno: Very high pitch Cassa for rim shot, wood blocks, fingers snap like sounds. This channel can produce some scratch noise when you move the frequency pot, especially if you keep the resonance pot. to 0, this is normal.
• Legno CV: Add  cv control over frequency and resonance with cv amount.
• Piattino: Hi-hat module based around Cassa design with white noise and tow release envelope.
• Rullo: Snare drum Module, our version with trig mix and cutoff on noise.

All percussion module are 3U, 4HP or 6HP the CV version, and have tow trig input and a trig mix pot. accepting different signal :

Trig: short trig, less than 10ms will play one time, longer trig will play tow times.
Cv: you can use different cv signal like envelope, lfo for trig the modules.
Audio: cassa design is based around a stepped resonant filter, you can route audio signal to a trig input for filter and distortion effect.

TRIG MIX : The rhythm played by the Cassa is the sum of the tow trig IN1 and IN2.

The trig mix pot. adjust the mix between the tow trig input, great  for create poly rhythms.

If only IN1 or IN2 are plug the trig mix pot. adjust the level of the trig in signal.

FREQUENCY: Adjusts the pitch of the sound of Cassa, also affects the resonance.
Frequency and resonance are related.

RESONANCE: Adjusts the resonance, ie the damping time of the Cassa. 

Beyond a certain level the Cassa go into permanent oscillation, the level at which the oscillation begins varies with frequency.

If you keep resonance pot. to 0 moving the freq. pot can cause some scratch noise, this is normal.

DISTORTION: Adjusts the level of Cassa signal distortion.

FREQUENCY & RESONANCE CV IN: These are cv input to control the frequency and resonance of the module with cv, a cv in amount is available.
The cv control is made with a vactrol connected in parallel with the frequency and resonance potentiometer, this way you can set the range of modulation.

New Module Rullo (snare drum)

Trig Mix : mix between trig in 1 and trig in 2 

Decay : regulate the decay of noise signal

Freq: Regulate the frequency of tom sound

Cutoff : rugulate the cutoff frequency of noise signal

Multi Ritmi

 

Multi Ritmi is the Multicassa analog clock divider sequencer, 3U 10 HP.

It's outputs four, +5v 10ms trig signals and Tree trig mix signals, it has an internal tempo generator with clock in\out and a reset button.

Apart from Multicassa It adds a chaos switch for change the groove adding more chaos\instability to analog clock dividers.

With Multi Ritmi you can now compose your favorite modular Multicassa, choosing from different percussion modules.

Manual:

 

Clock DIVIDER 1\2\3\4 : 

These pots set the clock divisor number, if the potentiometer all the way left, to each pulse of the Tempo white LED will have divisor x 1, slowly moving forward we will have dividers more high 2\3\4... the max divider is about 64 (potentiometer fully right).

 

Trig Out 1\2\3\4 :

Trig outputs a trig signal, +5v, 10ms.

 

Trig Mix Out 1\2\3 

It output a trig mix signal, out1 mix1\2, out2 mix 2\3, out3 mix 3\4

 

Tempo pot. :

The tempo pot adjusts the speed of the internal clock generator, and then all the rhythms. 

All on the left, minimum speed, maximum speed all right. 

When you set the switch to external clock, the tempo pot. acts as a divider (clock prescaler) to the incoming clock at clock in jack.

Same way of the clock divider, in this case we will have the maximum speed with the potentiometer all at the left, dividing x1.

 

Clock out :

It outputs a +5v clock pulse signal according to tempo pot. and white led. 

 

Chaos switch:

When on chaos mode a certain instability is added to the dividers resulting in different groove, when off no effect.

 

Reset button:

This button reset all the dividers and the internal clock generator.

 

Power connector:

Multi Ritmi accept modular power +12v
