MUSICAL FEATURES

MATHS is a CV generation / modulation module that can be compared to the Swiss Army knife because of its versatility.It has two envelopes and LFOs (CH2 & CH1), and you can combine them with the plus α function to create a complex and musical envelope.In addition, patching can perform various functions such as trigger delay, envelope follower, and comparator.

The two channels that play a central role in MATHS, CH2 and CH1,
  • -SLEW(Input signal to SIGNAL In, CYCLE button OFF)
  • -AD envelope (Enter the trigger in Trig In and turn off the CYCLE button)
  • -Repeated AD envelopeLFO(In particular, do not input to SIGNAL IN or TRIG IN, CYCLE button ON)
Function as one of the. SLEW can input the gate signalASR envelopeIt can also be used as

The most important parameters of CH1 and CH41,Rise time / Fall timeWith the change of, the speed of the signal rise / fall changes as follows.
  • -When used as SLEW, the degree of change in input voltage is adjusted for rising and falling.
  • -Adjust attack time and decay time individually for AD envelope
  • -LFO adjusts the rise and fall times individually
RISE / FALL can be controlled by CV.

The remaining CH2 and CH3 are simple ± bidirectional attenuators / offsets.
In MATHS, these CH1 ~ CH4SUM or ORIt is also possible to synthesize in the form of to form a complex signal. Also installed on CH1 and CH4EOR (END OF RISE) / EOC (END OF CYCLE)The gate signal that informs the timing such as can be used for various purposes. manualThere are lots of patch explanations and TIPS in the latter half of, so please try various patches.

Tips

Signal In / Trigger In

When inputting the trigger signal to MATHS, there are the following differences between Signal In and Trigger In.
  • In Signal In, the fall starts as soon as the trigger is turned off.
  • In Trigger In, the fall starts after the specified rise time.
So, when the rise time is set to be long, if you input a trigger to Signal In, the release will start with the envelope hardly rising, but in the case of Trigger In, the rise → fall will be performed according to the set time. .

Also, in Trigger InRetriggerPlease note the presence or absence of. Even if there is an input in Trigger In when the envelope is raised, the envelope willNot retriggered.This property is very useful when creating a loose envelope from a busy trigger pattern or when using it as a trigger delay as described below. Due to this property, the EOC / EOR output isClock dividerCan be made to work like.
 

LOG / LIN / EXP

In MATHS, CH1 and CH4 envelopes areCurve characteristicsCan be adjusted in a very wide range. LOG has a pressure envelope, and EXP has a super snappy and percussive envelope. The adjusting ability of this curve is also a big feature of MATHS.
Log Curve Curve

When the knob is close to Log. The envelope will have a bulging curve.

Exp Curve

When the knob is close to Exp. The envelope will be a curve that bulges downward.

Also, by self-patching the envelope into the CV input of its Rise / Fall time,You can also create curves with different characteristics using RISE and FALL.

If you set the curve characteristics to LOG and modulate the Fall with your own envelope, you will get an envelope like the one above. The variable output is used for modulation so that the modulation amount can be adjusted with the atte inverter, and the atte inverter is made negative. Patch the Unity output to the desired modulation destination.
See also the patch per 50 seconds in the "MATHS Advanced Envelope Techniques" video below.

Audio rate

By shortening RISE and FALL extremely in CYCLE mode, CH1 and CH4 are1kHzSince the frequency can be raised up to, it becomes an instant oscillator. Since all channels can process up to the audio rate, it can be used as a mixer, etc. It can also be used as an envelope follower by inputting audio signals to CH1 and CH4 and setting RISE and FALL appropriately. If RISE and FALL are lengthened, the cycle becomes25 minutesIt can be as long as it exceeds. Therefore, it is possible to design the envelope as a big flow in one song.
 

Trigger Delay / VC Gate

From End Of Rise, the input trigger signal is output with a delay of the rise time, and gate ON continues for the fall time. In this way, the function to delay the trigger and output as a controllable gate,Trigger delay / VC gateThis is a very useful function when creating rhythms in a modular fashion. It can be used in a more organic way by combining it with the above retrigger properties.
