The MULTI CASSA is an electronic Eurorack module for percussion sound and special FX. Created by LEP Laboratories, the MULTI CASSA module takes inspiration from the Leploop synth. MULTI CASSA is a combination of two modules with different pitch settings, the first maintains the original pitch, the second increases the pitch to recreate the sound off high tom or snare drum.
TRIG MIX: The rhythm played by the MULTI CASSA is the sum of the two trig IN1 and IN2. The trig mix pot adjusts the mix between the two trig input, which is great for creating polyrhythms.
FREQUENCY: Adjusts the pitch of the sound, also effects the resonance.
RESONANCE: Adjust the resonance, i.e. the damping time of the case. Beyond a certain level the MULTI CASSA can go into permanent oscillation. The level at which the oscillation begins varies with frequency.
DISTORTION: Adjusts the level of signal distortion.
Notes: The Lumanoise V4 has 4 trautonium-like sub-oscillators. T Master oscillator under LDR control and 4 sub-oscillators were used, where you can set the division frequency of the T Master Oscillator Divider. Each oscillator has a volume pot. It's possible to connect an external LDR, a pot, a variable resistor or a high/mid/low switch for the T Master oscillator range. The filter cut-off of the 12 db low pass resonant filter can be controlled by the potentiometer or the photoresistor.
Notes: Lumanoise V3 has 2 sawtooth oscillators; SAW1 for bass frequencies and SAW2 for high frequencies, a white noise generator and a 12 db low pass resonant filter. The oscillator pitch is controlled by a photoresistance sensitive to light intensity.
- High/mid/low switch for the oscillator range
- 12 db low pass resonant filter
- Mini jack in for adding an external photo resistor, or a potentiometer for external oscillator pitch control
Cymbal drone generator featuring six fixed frequency square wave oscillators
Notes: The 808 cymbal drone generator uses 6 fixed frequency square wave oscillators. The oscillator frequency came from the cluster oscillator circuit used in the TR808 drum machine for creating cymbal sound, in fact these are the harmonic frequencies of the sounds of metal plate. Each oscillator has a volume pot, and a 12 db low pass resonant filter - the filter cut-off can be controlled by the potentiometer or CV.
Drum & filter module with very high pitch range for rim shot 4HP
Notes: Legno is percussive instrument based around cassa design with very high pitch range for rim shot, fingers snap, high tom like sound.
Basically Cassa, Bongo and Legno are the 3 multicassa channel in eurorack format.
All the 3 module share the same design with different pitch range, cassa low range, bongo one octave higher range and legno super high range.
Notes: Cassa CV comes equipped with two trigger inputs. A mix potentiometer enables the user to crossfade between both instances. Thanks to the dual design, it is possible to mix signals coming from two sequencers or other trigger sources to create complex polyrhythms, fills and such.
For shaping bass drums, Cassa CV offers frequency and resonance potentiometers. Additionally, there are control voltage inputs plus attenuators for both parameters. Furthermore, the strength of incoming trigger signals influences the sound. Low resonance settings lead to crisp, rather harsh kicks. Using the frequency potentiometer, it is possible to vary between slim and extremely bulgy results. High resonance values make the circuit scream bloody murder.Still not hardcore enough yet? Then dial in the Cassa CV's distortion circuit and listen to some of the most obnoxious bass drums on planet earth.
As the Cassa CV is basically a filter, which gets excited by trigger signals to generate sound, it is possible to use the inputs for audio material as well. The results don't have much in common with what you might expect from a VCF. The module colors audio material intensely, squeals like a stuck pig and adds a boatload of dirt.
Bass Drum & Filter Module with two trigger inputs 4HP
Notes: Cassa has two trigger inputs between which you can crossfade unsing the MIX potentiometer. So simple and so brilliant ... mix two different trigger sequences, blend between them, create fill-ins or connect a manual gate and fire some extra drums with your finger!
FREQ sets the drum frequency, RES controls decay time; at long decays the Cassa starts oscillating in an obscure way and starts screaming (no, it's no self- oscillation, that's schreaming!). DIST is a pretty wild distortion. Gabba musicians will love it!
Attention: module abuse!:
As the module is based on a filter which resonates when being "pinged" by a trigger signal at the audio input and then creates a percussive sound it's not far-fetched to inject audio signals instead triggers int othe Cassa. FREQ is cutoff frequency and RES the filter resonance, just as expected. But both act pretty unusual in this case for a filter. It phases more than it filters, the resonance roars and the distortion does the rest...
Instead of using two audio signals you might use one trigger and one audio signal - and the Cassa will indeed generate a drum and process the audio signal at the same time. Weird but possible. Instantly it was possible to generate a wobbly Skrillex simulation, read: saw mill dubstep aka "Filth".
Bongo CV with two voltage-controllable parameters 6HP
Notes: Bongo CV comes equipped with two trigger inputs. A potentiometer allows you to crossfade between them. The sound varies depending on the level of incoming trigger signals. With just one input patched, the knob can be used as a tone control for treble attenuation. This behavior is not surprising, as the Bongo CV is basically a pinged filter. Accordingly, the sound shaping parameters are called frequency and resonance.
The cutoff potentiometer is slightly erratic. Small changes sometimes have a huge impact on the module's sound. The resonance leads the Bongo CV rather early into violent self-oscillation. Both sound shaping parameters feature CV inputs plus attenuators.
The filter is followed by a distortion circuit. It not only adds dirt to sounds, but also removes a lot of bass. - Very important for creating "real" bongos. - Without any distortion, the results are more reminiscent of bass drums or low toms.
The inputs can not only be fed with triggers, but audio signals as well. Patched like this, the Bongo CV acts as a filter. The sound qualities remain the same. Depending on the knobs' positions, the sound is rough to brutal and more or less dirty.
