Bit Trig Sequencer

Bit Trig Sequencer is a simple trigger sequencer which has a unique pattern generator.

It consists of 4 lanes of 8-step trigger sequencer.

Compute a Sequence

The module generates a sequence consisted of 8 steps of triggers when it runs the "Compute" function.

"Compute" function interprets the "Computational Value" as an 8-bit number and each "bit" of the number forms a state of a step in a sequence.

First (leftmost) step of the sequence is the 8th bit of the Computational Value and the last (most right) step is the 1st bit of the value.

The 8th bit becomes an indicator of the "sign" of the value if the Computational Value is a negative value. If you want to set a first step of the sequence "on", setting negative values to the Computational Value is an easier choice.

The range that the Computational Value can handle at a time is "±0 to +255" or "-127 to +127." Since the internal calculator changes its interpretation of the Computational Value automatically between "unsigned 8-bit variable" and "signed 8-bit variable", you don't need to worry about strict type of Computational Value.

Controls and I/O

Knobs

• CV1-4 Gain: changes the level of incoming signal from each of the input sockets.

Buttons

• +/x: changes the way of calculating the Computational Value. Calculation always goes through left (CV In 1) to right (CV In 4) regardless of the setting of these arithmetic operations. If a input socket is empty, the value from that socket is simply ignored. In case you want to have "x0.00v" in the calculation, you need to inject a signal of 0 volt.
• Compute: runs the Compute function and it applies the result of computation to the selected lane.
• Step: advances the position of the sequence a step at a time of the button pushed.
• Select lane1-4: selects a lane for emitting triggers and computing.

Switches

• Calculation Mode: The calculator constructs voltage value from CVs as the labels shows. In Mode 1, voltage value of 1v becomes 100 of Computational Value. In Mode 2, CV values are multiplied by 100 before they get into the calculator and 0.01v of voltage value becomes 100 of the Computational Value.
• Computational Value Lock: changes the state of Computational Value between editable or not. When the value is locked, the result of calculation of CV value are not refreshed and the latest value is kept for Compute function.
• Track Select Mode: switches how the selection of the lane of tracks is changed when the trigger is sent to the Seq Select Trig Input sockets (details below Inputs section). It only affects the behavior of Seq Select Trig In 1-4 input sockets and selecting lanes by pushing buttons is not affected.

Label

• CV In 1-4: Voltage value of incoming signals is shown here after the gain change is applied.
• Computational Value: shows the result of calculation of CV values. Also you can edit the value manually by clicking on the label or dragging the mouse up/down on the label. If you edit the value manually, the module automatically changes the state of Computational Value Lock to locked.

Grids

• Seq Lane1-4: displays a sequence. Also you can edit sequences directory by left-clicking or dragging the mouse.

Inputs

• CV In 1-4: gets CV signals for source of calculation of Computational Value.
• Compute Trig In: runs the Compute function and the function applies the result of computation to the selected lane.
• Seq Select Trig In 1-4: When it received a trigger signal in Direct Mode of the Track Select Mode, it selects corresponding lane as current selection of the sequence. When the Track Select Mode switch is set to Cycle Mode, all of the Seq Select Trig Ins are functioned to cycle the selection of lane.
• Step Trig In: advances the position of the sequence a step at a time of receiving a trigger signal.

Outputs

• Seq Trig Out: emits the sequences of trigger signals from selected lane.
• RTB(Return To Beginning) Trig Out: emits a trigger when the position of the sequence returned to the beginning.
