Envelopes and complex functions
raindeer, 19.02.2021
The different coloured lights and CV assignment options take a bit of getting used to. But basically this can be either
1. just a simple and easy to use quad AD\AR Envelope and LFO or
2. an amazingly deep source of complex functions and modulation

If you only need #1 then its extremely playable but for #2 there are definitely non-intuitive button combinations and alternate modes to remember to get the full Quadrax value. That is the price of having all this in 14hp.

Verbesserte Version des beliebten 4-fach Funktionsgenerators
Tos , 10.01.2020
War der Vorgänger Quadra schon ein Modul, dass in keinem Eurorack System fehlen durfte, bietet der Quadrax nun – bei nur 2 hp mehr Platzbedarf – erheblich mehr Funktionalität: Insbesondere können Kanäle nun wahlweise auch als Burst Generator arbeiten, intern (ohne einen auch schon früher erhältlichen Expander) für komplexere Hüllkurven verkettet werden, und es können bis zu 4 Parameter spannungsgesteuert werden. War die Kurvenform im Vorgänger nur schaltbar zwischen linear und logarithmisch, ist sie hier stufenlos regelbar – und zwar auch in den exponentiellen Bereich. Bursts können nicht nur in Anzahl und Form eingestellt, sondern auch mit ab- oder anschwellender Amplitude erzeugt werden.
Der größere Funktionsumfang bedingt zwar etwas mehr Einarbeitung – so erfordert die Kompaktheit beispielsweise verschiedenfarbig leuchtende Taster, aber für Menschen ohne Farbwahrnehmungsprobleme ist das Modul durchaus beherrschbar. Die Konfiguration bleibt nach einem Powercycle erhalten.

WOW
Monkey McMonk, 22.12.2019
Envelope und LFO mit Mod-Matrix, 4-Voice Oscillator mit 1v/Oct und so vieles mehr. So viele Funktionen, die sinnvoll und durchdacht sind. Da hat sich einer gedanken gemacht. Bedienung auf Grund der Vielfältigkeit der Matrix etwas komplex, aber wenn man das Manual ackert bekommt man das auch hin. Als 4-Fach Oscillator auf jeden fall brauchbar da man die Waveforms Morphen kann (ähnlich Wavetable?) und diese auf 1v/Oct ansprechen. Um direkt auf C zu stimmen braucht man etwas chirurgische kenntnisse! :D Verarbeitung wie von Intellijel gewohnt, top!
