ALM Busy Circuits Boss Bow Two
Dual-channel CV bow/exciter for physical modeling synthesis
8 HP Eurorack module
Boss Bow Two is a dual-channel touch-responsive controller designed for exciting physical modeling synthesizers. Each channel converts touch gestures into CV signals representing pressure and position, along with gate outputs. It acts as an expressive bow or exciter interface, translating nuanced finger movements into control voltages that bring physical modeling patches to life.
Features
- 2 independent touch-responsive channels
- Pressure CV output per channel
- Position CV output per channel
- Gate output per channel
- Touch-responsive playing surface
- Designed for physical modeling excitation
Controls & Jacks (21)
- Mode LED Group — LED cluster showing the current operating mode. Lights indicate Step, Voltage, or Gate mode selection.
- Control Attenuverter — Attenuverter for the Control CV input. Scales and inverts the incoming CV signal. In Voltage mode, adjusts the sensitivity of CV-to-I/O addr
- Offset — Bipolar offset knob that adds or subtracts voltage from the control signal. Use to manually set the active I/O in Voltage mode, or to bias t
- I/O 2 — Bidirectional I/O jack 2. In Step mode, becomes active when the sequencer advances to position 2. In Voltage mode, selected when CV maps to
- I/O B — Main signal I/O for the right bank. Bidirectional common jack — signal flows between this jack and the currently selected numbered I/O. Acce
- I/O 3 — Bidirectional I/O jack 3. In Step mode, becomes active when the sequencer advances to position 3. In Voltage mode, selected when CV maps to
- Clock — Clock input. In Step mode, each rising edge advances to the next I/O in sequence. In Voltage and Gate modes, can be used as a reset trigger.
- I/O A — Main signal I/O for the left bank. Bidirectional common jack — signal flows between this jack and the currently selected numbered I/O. Accep
- I/O 4 — Bidirectional I/O jack 4. In Step mode, becomes active when the sequencer advances to position 4. In Voltage mode, selected when CV maps to
- Reset — Reset input. In Step mode, returns the sequence to I/O 1. In Voltage and Gate modes, resets internal state to the default position.
- I/O 5 — Bidirectional I/O jack 5. In Step mode, becomes active when the sequencer advances to position 5. In Voltage mode, selected when CV maps to
- I/O 1 — Bidirectional I/O jack 1. In Step mode, becomes active when the sequencer advances to position 1. In Voltage mode, selected when CV maps to
- Control — Control CV input for selecting the active I/O. In Voltage mode, 0–5V maps across the numbered I/Os for CV-addressable switching. In Step mod
- I/O 6 — Bidirectional I/O jack 6. In Step mode, becomes active when the sequencer advances to position 6. In Voltage mode, selected when CV maps to
- I/O 7 — Bidirectional I/O jack 7. In Step mode, becomes active when the sequencer advances to position 7. In Voltage mode, selected when CV maps to
- I/O 1 LED — LED indicator for I/O 1. Lights when I/O 1 is the currently active channel. In Gate mode, indicates gate/trigger activity on I/O 1.
- I/O 2 LED — LED indicator for I/O 2. Lights when I/O 2 is the currently active channel. In Gate mode, indicates gate/trigger activity on I/O 2.
- Mode — Mode button — cycles through three operating modes: Step (sequential switching on clock), Voltage (CV-addressable selection), and Gate (inde
- Step — LED indicator showing Step mode is active. In Step mode, the clock input advances through I/Os sequentially.
- I/O 3 LED — LED indicator for I/O 3. Lights when I/O 3 is the currently active channel. In Gate mode, indicates gate/trigger activity on I/O 3.
- Address — LED indicator showing Voltage mode is active. In Voltage mode, the Control CV input selects which I/O is connected to the common jack.
