A Technical Note on the Hardware
The new Make Noise DSP hardware features 2 Inputs and 8 outputs of low noise, high dynamic
range, fully DC Coupled Digital Signal Processing power. We used a 5 volt CODEC which helped us
achieve excellent SNR and yields an impressive input dynamic range that is around 12 to 30 dB
better than possible with low-power 3.3 volt CODECs commonly used in synthesizer modules. Best of
all, this new DSP platform is DC coupled, resulting in nearly flat frequency response down to
0Hz, giving the possibility for a huge, clean sound. Having 8 outputs instead of the more
common 2 IN/ 2 OUT configuration allows us to approach simultaneous outputs previously seen only
in our analog modules such as QPAS, XPO or DPO. The signal processing is achieved with modern ARM
Cortex-H7 MCU running at 480MHz. Plenty of SDRAM and FLASH memory means big buffers and
larger stored tables, and that ultimately means code can run faster. Firmware updates are handled
using the onboard micro SD Card interface so updating firmware is as easy as dragging the new
firmware file onto the Micro SD Card.
