"This module is a Dual ADSR similar to the envelope generators in the Roland 700 and 100M modular analog synthesizers. The AM8705 contains two identical traditional ADSR format envelope generators with variable Attack, Decay, Sustain and Release. The module uses 30mm travel slide potentiometers and has toggle switches to switch between 2 different set of timings - slow or fast."
"This module contains two envelope generators each with 3 timed stages: Attack, Decay, Release. The Sustain control adjusts the level to which the Decay time reduces to. Both ADSR's are triggered together by an internal gate signal from the standard Doepfer 16 pin bus, or a front panel push button (MANUAL GATE), or individually via a gate signal connected to the front panel Gate jacks (GATE1, GATE2).
The standard duration of each stage is 10 seconds, but each ADSR can be switched using the TIME toggle switch into a fast timing 1/10 the duration. This enables fast envelopes to be generated. Two identical control voltages are available for each ADSR, making it easy to patch an ADSR into both a VCF and VCA simultaneously. The gate signal is displayed for each ADSR via a dedicated LED. Each ADSR generates a control signal from 0V to +10V.
There is a Red gate LED for ADSR1 and a Blue gate LED for ADSR2. The toggle switches have colour coded caps (Blue and Red) and the single gate switch is a Red push button button."
"This module is a replication of the Jupiter 6 voltage controlled filter which comprises two 2-pole OTA filters in series, and was launched in 1983. Each 2-pole filter can be switched into either Low Pass or High Pass modes providing three VCF modes all with variable resonance:
24dB Low Pass Filter
24dB High Pass Filter
12dB Band Pass Filter
This voltage controlled filter has a more aggressive sound than a simple 4 pole OTA based filter, along with a lot more flexibility...
This module is a multi-mode voltage controlled filter with front panel controls for adjusting the Cutoff Frequency and Resonance as well as the level of 2 control voltages and 3 audio signal inputs. There are six 3.5mm jack sockets on the right of the front panel; the filters audio output, 2 control voltages and 3 audio inputs. The filter topology can be adjusted using two front panel latching push buttons.
The filter has two 2-pole OTA filters in series, and the blue and grey push buttons select from 4 filter modes, each sounding different:
24dB Low Pass Filter - Blue and Grey OUT
24dB High Pass Filter - Blue and Grey IN
12dB Band Pass Filter - Grey IN and Blue IN
12dB Band Pass Filter - Grey OUT and Blue IN"
