Synthesizer Accent and Accent Out

The Accent function of the internal synthesizer and the Accent Out signal are both

activated when any of the following are true:

1 The internal sequencer is running and an accented note is being played.

2 The internal sequencer is not running, but the last note had the accent on.

3 The Accent In socket has more than about 2.3 volts going into it.

4 The red “Accent Pushbutton” on the right of the front panel is pushed.

Point 2 is worth remembering, since you may be driving the Devil Fish from an external

CV, Gate and perhaps from and external Accent voltage, but you may not hear every note

being accented in the sound coming from the machine. It may not sound this way, but the

constant activity of the Accent MEG LED, and the lack of activity of the Normal MEG

LED should alert you to the problem. The likely cause is that you were playing the

machine from its internal sequencer and stopped it on an accented note. The solution is to

start it again and stop on an unaccented note, or to turn the machine off and on again.

According to one report, depending on the contents of the memory and the settings of the

Track/Pattern and the Mode switches it is possible that when you turn the machine on, the

internal sequencer will be in this accented state. I have not observed this, but it can

probably be fixed by clearing pattern 1A, or the first pattern of the song in whatever

group you have selected when you turn the machine on.

Synthesizer Gate and Gate Out

The Gate Out follows the Synthesizer Gate which is on when one or more of the

following are true:

1 The internal sequencer is playing a note. This will happen when the sequencer

is running or when you are playing notes in the programming mode.

2 The Gate In socket has more than about 3.5 volts (1.5 volts for version 2.1C

and earlier) coming into it.

The Slide In voltage is above its second threshold. (Version 2.1D and later

only.)

If you are playing the Devil Fish from external CV and Gate, and you have the internal

sequencer running as well, then both these will be driving the synthesizer gate, so you

may get weird sounding notes. You can use this to advantage if you want some out-of-

sync notes playing in addition to the normal ones. You can also have the machine running

from external CV and Gate, but add in your own notes (Gates) by putting the machine

into Pattern Write, Pitch Mode, and pressing any of the 13 note buttons.

The Devil Fish uses the standard TB-303 Gate Out circuit. This is driven by a diode and

a 1K resistor inside the machine. It goes high to 12 volts when the Gate is on. If you short

it to ground (for instance as you plug a lead carrying this signal into a socket), the extra
