WHAT CHIPS ARE USED?
Want to know what's inside our machines? The NF-1(m) contains two processors:
- a DSP56725 dual core DSP-processor at 250MHz dedicated to sound synthesis,
- and one 16MHz PIC18F67K22-microcontroller to collect data from the knobs & buttons, control the LCD-screen & leds and manage midi communications.
Furthermore there's a DA-converter, Cirrus Logic's CS4392 (CS4334 on first production batch) and a few flash memory chips 24LC256.
The DSP56725 is a member of the famous DSP56-family of DSP processors by Freescale (Motorola) that populated the Access Virus, some of Waldorf's synths, Clavia's Nord Leads and many more...
Wow, wow, wait a second... Does that mean the NF-1(m) sounds like a Virus or a Nord Lead? No, of course not! Unlike analog synths, where the sound is determined by the sound chips and electronic circuits, the sound of a digital synth is defined by the program inside the chip, not by the chip itself. And that program is 100% genuine Modor built!
The DR-2 also contains two processors:
- an ADSP-21489 floating point DSP-processor at 400MHz dedicated to sound synthesis,
- and one 16MHz PIC18F67K22-microcontroller that runs the step sequencer, collects data from the knobs & buttons, controls the LCD-screen & leds and manages midi communications.
Furthermore there's a DA-converter, Cirrus Logic's CS4385 and a few flash memory chips 24LC512.
Modor had to move on from the formerly very popular DSP56-family because these are going out of production. So we arrived at the powerful SHARC DSP-processor family from Analog Devices. A design step that took quite some time to adapt to, but which we don't regret at all!
And Modor's Eurorack modules? They are all based on a STM32 processors (STM32F405). They have Cirrus Logic's CS4392 DAC (Noisy Oscillator) or CS4272 codec (Formant and Comb Filter) on board.
