The legendary 2500 Series brings classic sequential control to your Eurorack system with the CLOCKED SEQUENTIAL CONTROL MODULE 1027, an authentic 8-step 3-channel sequencer that captures the essence of vintage modular synthesis. This professional-grade module features an integral 8-step counter equipped with a substantial rate control knob and low/high range switch, giving you precise tempo control for crafting your musical sequences.
Built for both studio precision and live performance flexibility, the 1027 includes pulse width control and external control switching capabilities. The module’s intuitive interface features a large illuminated on/off switch alongside manual step and reset switches, providing hands-on control when you need it most.
Three sets of eight colour-coded knobs offer comprehensive command over the CV output voltages across all three channels. Each step in your sequence can independently control external VCO frequency or filter cutoff frequency, allowing you to create complex, evolving patterns that breathe life into your modular compositions.
- Classic 1027 clocked sequential controller module from the '70s
- Authentic reproduction of the circuitry from the "2500" Series
- Contains an integrated circuit 8-step counter and 3 channels (A, B and C) of control voltages
- 8 rows of 3 controls provide 3 independently adjustable voltage outputs for each step of the counter
- Built-in time base generator allows the sequencer to step automatically
- Each row has an adjacent LED indicator to display the sequencer count
- Illuminated push button is used to start and stop the internal clock
- Rate of the internal clock can be adjusted from a stepping rate of 20 per minute to 400 per second by adjusting the Pulse Repetition Frequency control and the external rate control signal
- Internal clock can be turned on and off by applying pulses on the appropriate input connections
- Clock pulse width and duration of the step voltages is adjusted from 0 to 100% by the Pulse Width control and the external width control signal
- With the clock turned off the sequencer may be stepped along and reset manually using the front panel push buttons
- Control voltages on channel A, B and C range between 0 to 10 V
- The 1027 can be used to control other 2500 Series modules including the 1026 Preset Voltages or 1050 Mix Sequencer modules
- Cable connections are provided on the rear of the PCB for this purpose (cable included)
