Notes: Advanced generative sequencer featuring mutes per channel and transposition facilities.

Akropoli is an extension and enhancement of our successful Little Melody and High Towers modules, offering the features of both of these modules as well as some of it's own unique features such as mute buttons per channel, manual transpose knob and 1V/oct transpose CV input. Akropoli operates using Frequency Central's proprietary TOOL V2 code, and can count in integers as well as multiples for even more subtle and evolving variations.

Akropoli is a generative sequencer based around clock divisions and a chromatic quantiser, used to create in-the-moment licks and riffs. It is more that the sum of it's parts.

Akropoli's internal operations can be considered as 4 clock dividers patched into a CV mixer via attenuators. The attenuators select notes over a 5 octave range, the clock dividers determine how often those notes are added to the mix. The final output of Akropoli is quantized chromatically for fast set up and continuously pleasing results. Akropoli has an onboard transposition knob, as well as a 1V/oct transposition CV input.

The 4 clock dividers are labelled A, B, C, and D. They all receive clocks from the same source, the divisions may be selected using the presets and the individual division selectors. The clock dividers can be set to count up, down, or to one of a variety of modes that move between counting up and down. For further information on Presets and Modes see the Little Melody User Guide.

Additionally, each clock divider has it's own binary output (either high or low), these 4 outputs can be used to clock/gate/trigger other stuff on other modules to great effect.

Notes: A couple of years back, Frequency Central developed Cosmic Background as a standalone percussion voice. The concept was to bundle all required sub-modules behind one panel, pre-patched, yet also fully modular, with each sub-module having its own inputs and outputs. This proved to be a very popular product, but Frequency Central decided to replace Cosmic Background's noise generator with a VCO (and do a few other tweaks), creating a cute little fully modular synth voice ripe for sequencing - and that's how Dark Star was born!

Dark Star consists of 4 sections:

Voltage Controlled Oscillator based on AS3340 with sawtooth, triangle and pulse waveforms
Voltage Controlled Filter with lowpass and highpass options, Drive control, Sweep control which attenuates amount of Release CV
Release generator with CV input for voltage control of release time. Option for sustain via jumper on rear panel.
Voltage Controlled Amplifier
Together they form a pre-patched super versatile analogue synthesiser voice.

Additionally, each section is fully modular in it's own right, so there are patch points for:

1V/oct CV input
PWM CV input - attenuator doubles as manual pulse width when no external signal is present
Gate input for Release or Sustain/Release
Release CV input for voltage control of Release time
VCF audio input with attenuator, for introducing external audio
VCF CV input with attenuator (1V/oct CV is normalised to this input)
VCA audio input (VCF is normalised to this input)
VCA CV input (Release CV is normalised to this input)
Release CV output
VCO audio output
VCF audio output
VCA audio output

Here are some useful patches to try:

Release CV output to PWM CV input, for swept PWM
VCF OUT to VCF IN, thickens and further overdrives the filtering
VCO OUT to VCF CV input, for fizzy FM of the filter
Use a multiple to patch 1V/oct to Release CV input, lower notes will have longer release, higher notes will have shorter release
