Introduction Soundmachines DC1drumcomputer is a powerful drum sequencer that includes traditional functions, storage and recall functions and an innovative CV control of many (most!) parameters of the sequences via four totally configurable inputs. The led matrix display shows at first glance the pattern and the active steps and the user can easily insert hits via two encoders (in an X-Y fashion).
Care and feeding The soundmachines DC1drumcomputer module has a Doepfer compatible power connector and need 60+60mA (at maximum illumination, see menu) to work. By default the trigger voltage jumper on the back is inserted to provide 5V triggers. It is possible to switch it to output 12V triggers.

A sequence is defined as a set of tracks, the sequence speed, the individual tracks lenght, the gate lenght, the shuffle and the 4 CV bound functions. Please see the Appendix "SD card management" store button: As above, the user is prompted with a graphical display of the possible locations where to save the present pattern.

In external clock mode, a pulse (low-to-high) on reset input 'resets' the current sequence, i.e. the current sequence (pattern) is executed starting from the first step (restart from the first step). start/stop: this input, along with the button, starts and stops the sequence.

Menu Items: GATE LENGHT (GATL) (1..12) This is the lenght of the gate/trigger signal. It is expressed in 24th of a step, default maximum value. Each sequence has its own gate lenght value stored in memory. ROLLS TYPE (ROLL) (2,3,4) ...

2. LOCK TIME (LCKT): only the TEMPO parameter of the patterns played by DC1 remains unchanged, and TEMPO is equal to the value set on the 'basic pattern' that is the time of the first pattern of the song or the loop. In this case a change to the value of the parameter TEMPO, modifies TEMPO of the basic pattern.

SONG MODE (SNGM) OFF (default, exit from SONG MODE) SNG2 P1-P2 (the active pattern P1 and the following one are cycled) SNG4 P1-P2-P3-P4 (the active pattern P1 and the following 3 are cycled) SNG8 P1-P8 (the active pattern P1 and the following 7 are cycled) ...

CVx modes: LOOP1 (LOP1): each rising edge on the CVx input selects the next sequence and loops at the end of the available memory (so 64 or 128 seq). The new pattern is started at the end of the current one. (*) LOOP4(LOP4): each rising edge on the CVx input selects the next sequence starting from the active one until the fourth.
Page 10
FILL-IN A-H (FILa-FILh): the rising edge on the input triggers the start of a 'fill' pattern and at the end the sequencer returns to the original sequence. The fill- in patterns are ALWAYS the last eigth of the memory (57-64 in case of the first release and 113-128 in case of the second release of firmware and the presence of the SDcard).

TRACK GATE LENGTH (TGL1-TGL8): the input voltage changes the gate length of the track. The CVx analog value is mapped linearly into the corresponding track gate length. TRACK MUTE 1-8 (MUT1-MUT8): a high level on the input "mutes" instantly the output of the corresponding track.

How to build a Song, numbering of the sequences in memory 1. Load from memory with the load button the 'base pattern' (i.e. the first) of the song. 2. Set the song mode and the lock (if you want to lock all or some of the parameters of the song), and begin to compose the tracks of the first pattern.

Step 4. Keep inserted the SD card and wait for the program to start again with the scrolling text 'soundmachines'. After the program is started, press the load button for 3 seconds: in this way the DC1 drum reads the file 'SEQUENCE' on the SDcard which contains the sequences in the format that it is expected, and loads its content, i.e.

Appendix: SD card management: When you boot a new firmware version, if you want to keep the changes to the sequences in flash, you must first save the image of the pattern and parameters (active sequences) on an SDcard as described in the subsequent paragraph ' Store the Sequences into the SDcard '.

Firmware Release 1.0 (F1.0) - Fixed bugs and added features: 1. When the DC1 drum displays parameter 'tempo', if you exit from the parameter setting without saving the choice (by pressing the left encoder), the beat time remains set to the last value shown on the display (it doesn't return to the original value).

(*) Preset Pattern - Legenda: BD = bass drum SD = snare drum clap RIM = rim shot CH = close hat OH = open hat low tom HT = high tom → Added the firmware release, accessible in the menu by pressing the left encoder (for ex.
