fmtribe's Introduction

FMTribe

OPL3 synth/drum machine/thingie focused on live jamming for DOS.

Tested only with DJGPP and a PC with a Sound Blaster-compatible soundcard.

Web version

Diego Dorado kindly ported this to the web using JS-DOS. Check it out here!

Download

Install a DPMI server if you don't have one. See here for instructions.
Go to releases tab to download binaries.
Unzip and run FMTRIBE.EXE.
Have fun!

Usage

Esc: Exit
F5: Play / pause
F7: Stop after bar (2 times, stop immeadiately)
F9: Tap tempo
Shift + F9: Toggle metronome
F10: Toggle "follow cursor"
Left: Move to previous frame
Right: Move to next frame
Up: Move to previous channel
Down: Move to next channel
Del: Clear pattern for current channel
Ctrl + Del: Clear pattern for all channels
Tab: Switch instrument editor for the current channel
M: Toggle "apply step changes to all frames"
P: Toggle "play channel instrument"
Z: Toggle "record steps"
Alt + Number: Mute/unmute channel

Step Sequencer

To toggle a step in the pattern of the 16-step sequencer, use the keys:

Q W E R T Y U I
A S D F G H J K

To select one of the eight channels, use keys 1 through 8. You can mute a channel anytime using Alt + NumberKey.

Press Alt + StepKey to define microsteps (upto 3 for now).

Instrument Editor

To customize the parameters of an instrument, press the Tab key, select a field and change its value. The parameters will update automatically if the step sequencer is playing.

Left/Right: Increase/decrease value for the current field
Up/Down: Move between parameter fields

Also, you can still change channels with the numbers from the instrument editor.

To change the base note of the instrument, use the keys:

  W   E       T   Y   U
A   S   D   F   G   H   J

as in a keyboard of one octave. To change the base octave, use PageUp/PageDown.

Source

To tinker with the source code, you need to install DJGPP and its C compiler. Follow the instructions here.

fmtribe's Issues

Draw icons for states, like "following", "recording", "apply to all", etc

Solo channels with Alt+Number

"Tap Tempo" is not working correctly

Set a range of allowed values for BPM (e.g. 20 to 300), and respond to a second tap as a "first" if time between these taps is out of range.
When changing BPM, sequencer should move to the nearest "beat" step immediately. For example, if on step 2, go to step 1 (first beat), if on step 3 or 4, go to the step 5, (second beat). This way, the player always taps exactly on a "beat" step.

Ask for user confirmation (with Y/N) when trying to exit and it is playing

Right now, Esc exits program immediately. If sequencer is playing, it should ask user first. Esc = N on confirmation dialog (so pressing Esc twice does nothing).

When stopping, the first step of the next frame is played

Step sound is played when "leaving" step instead of "entering"

You can see it clearly if you slow down the BPM by tapping slowly.
