Grand Terminal v2 Airways update: all zero delay filters and freezer


Published on Apr 30, 2018 TheEndorphines

"Cool features are coming with version 2 firmware for GRAND TERMINAL (code-name AIRWAYS).
All filters are now zero-delay feedback (ZDF) and audio freezer #8 effect.
Available to download right away, see details at http://airways.endorphin.es

Pairs well with Winter Modular Eloquencer!
Come over to Superbooth 2018 and sequence Endorphin.es with Winter Modular at our booth's table O510 + O511.
In the following modular jam, Winter Modular Eloquencer plays Grand Terminal and its track 8 controls Freezer on-off and CV defines the speed of grain.

What's new list:
GRAND TERMINAL V. 2 ‘AIRWAYS’ (30.04.2018)

- all zero delay feedback filters with audio improved quality and less noise at the output.
- filter #1: 24 dB/oct low-pass transistor ladder zero delay feedback (ZDF) filter with resonance volume compensation.
- filter #2: MS-20 zero delay feedback 12 dB/oct low-pass filter. That filter has very powerful resonance (be careful :) and is now instead 18db/oct diode ladder.
- filters #3-4: vactrol zero delay filters. Identical to stock vactrol ones but with zero-delay nature. #4th filter has resonance volume damping to prevent clipping at high resonance level
- filters #5-7: state variable zero delay feedback 12 dB/oct filters (low-pass, high-pass, band-pass). Hi-pass closes fully into high-frequency silence even with full resonance
- filter #8: is unchanged – comb filter, since isn't possible to have it with zero delay nature, however fixed 2 kHz noise in the audio output
- volumes of all 8 filters are equaled (in power) when X is fully CW and Y is fully CCW
- in secondary mode while choosing filter volume and panning: when panning crosses the exact center (equal of left and right channels), follow me green LED blinks
- when we switch from 8th effect to 1st - green LED blinks and from 4th to 5th - red one.
- effect #8: FREEZE effect (instead of previous chorus): when the tap is pressed (or fever CV gate is on), the audio is looped by the grain length of fever knob and by speed defined by pressure knob or pressure CV applied."
