Maths by Make Noise is by far the #1 eurorack module on Modular Grid - both in terms of rating and popularity. In this video, loopop explains what Maths is and why it's so popular.
Maths sounds complicated and if you've heard some of the terms used to describe it - an analog computer, a function generator and various other quadratic equations, it may seem a bit intimidating, but overall, it has three core components: attentuverters, a mixer and slew rate limiters.
1. Audio level control (for example, to reduce eurorack audio levels to line level)
2. A simple voltage generator
3. Mod depth control for external LFOs and envelopes.
4. Signal/waveform inversion
5. An audio mixer
6. Slew for glide/portamendo effects.
7. It has multiple ways to trigger envelopes.>
8. It can generate two separate AD (Attack-Delay) Envelopes.
9. Envelope curves can be linear, exponential, logarithmich, or any combination thereof, generating "sharkfin" type envelopes.
10. It can generate ASR (Attack-Sustain-Release) envelopes
11. Various type LFOs
12. Math can behave as a voltage controller oscillator (VCO)
13. By creating two VCOs and patching one to the other you can create FM style sounds
14. With a bit of patching, Maths can create extremely slow LFOs (up to 25 minutes)
15. Maths can behave as an envelope follower...
16. ... which can be used as Sidechain
17. It can be a simple clock...
18. ... and perform as a clock divider
19. You can mix envelopes and LFOs to create complex shapes, such as a fast LFO riding a slow LFO
20. The OR output can be used to create even more complex waveforms, as well as act as a rectifier that only allow positive voltages.
21. Maths can process sounds fimilar to a filter with optional resonance
22. In a pinch, Maths can act as a VCA
