Ground Control is a 42 hp Eurorack performance sequencer.
The sequencer has 4 tracks: three melodic tracks and a drum track consisting of 8 drum triggers and modulation/accent output. There are also dedicated mute buttons for each track, MIDI and USB-MIDI I/O, external CV and a 2-octave piano-style keyboard.
The keyboard serves for playing the melodies as well as entering the menus – in that method the module eliminates tedious menu diving.
Each track can contain 24 patterns, which can be played separately or chained together in any order. All those tracks are organized into 24 projects. The number 24 is associated to the 24 letters of the Latin alphabet.
Ground Control features very stable internal analog and MIDI clocks preserving low jitter operation, which is crucial for tight sequencing.
There is no typical 808/909-style sequencing. Instead the patterns are entered either in 101-style step input, live recording and can be adjusted using the 303-style editor.
2 octaves of keyboard, play sequences and grooves on the fly or use external USB/MIDI gear for DAW integration or to control external MIDI gear

4 tracks: drum track with 8 triggers and modulation and 3 melodic CV/Gate tracks – Velocity and CC is recorded from external MIDI.
three record modes: step input with step editing, live recording and step editor
Flame’s Chord Machine 2 comes equipped with a chord generator, an arpeggiator and a quantizer. The module generates tuned CV signals for up to five voices. You even don’t necessarily need an incoming CV to generate these output signals. You define a chord and an arpeggio based on internal note and tuning settings, these settings can be saved in lists that function as song lists or chord progressions, depending on how you use them. The arpeggiator output can alternatively be used as a very flexible quantizer. For a quantizer and chord generator module of this size it has a lot to offer. All in all, the module is very powerful, which also makes it complex – but it is worth taking the time exploring it!
The voices generated by the Chord Machine 2 can be spread over a range of eight octaves. 42 presets plus 16 user chords with up to four voices are available for musical experiments. Additionally, it is possible to choose between first, second and third inversion. All in all, musicians get access to 232 chords, which are playable within 54 preset and 15 user scales. Transpositions can be done via a CV input. The arpeggiator can run in several directions. The octave range is variable as well. Program and arpeggiator parameters are not only editable by hand, but can be modulated via a CV input as well. For synchronizing the module to other equipment, there is a clock input.
Module A-175 (Dual Voltage Inverter) is exactly what it says it is: two identical inverters, which will take a voltage and output it in an inverted form - so that an input of +5 V will be output as -5 V, an input of -2 V will be output as +2 V, and so on. Two LEDs give a visual indication of the (positive or negative) output signal.
