3.3. Sound generation / Signalpath

This is what is to be found under the hood of MAGMA´s sound generation. All sections are labelled in a

speciccolour,correspondingtoMAGMA´sfront-panellayout.

The sound sources are the voltage-controlled oscillator (VCO) and a sub-oscillator (SUB), phase-synced to

theVCO.Theyputtheirwaveformsintothemixerandfurtherintothevoltage-controlledlter(VCF)andthe

voltage-controlledamplier(VCA).Thereisalsoanexternalinputfedintothelter/amplier.Havealook

at the two envelope generators and the way they are connected to their destinations: ENV2 controls the

VCA, ENV1 can be inverted and controls VCF and VCO pitch. LFO 2 controls the mixer, LFO 1 is connec-

ted to VCO pitch as well as to the pulse-width of the square-wave. Its modulation curve can also be inver-

ted.AtleastwendMIDIdata(ortheon-boardsequencerrespectively),controllingpitchandtriggering

4. PROGRAMMING SECTION

Here you will learn all about MAGMAs programming section, introduced on page 12.

4.1. Preset / Pattern Handling

Presets and Patterns

First of all, we should distinguish between presets and patterns. A preset contains all the sequencer set-

tingsplusaspecicsoundsetting.Apatternconsistsonlyoutofthesequencersetting.Thatmeans,when

changing a preset, pattern and sound will change. When changing a pattern, the sequencer will play

something different but the sound currently selected remains the same (the sound, not necessarily the

song…).

Memory Architecture

TounderstandMAGMA´smemoryarchitecture,pleasehavealookatthefollowinggure.Therearefour

banks of eight sub-banks each. Each sub-bank contains eight presets. This makes a total of 256 presets.

Exactly the same goes for the patterns. That´s quite a lot of fun to be had.

4.1.1. Loading a bank
