Version: v0.1c

Description:
Here's a drum machine, or beat maker. I started making another puzzle game, but it turned into a little music making program instead. With this you can make drum beats using 14 drum instrument samples.

Controls:
L Load Pattern
S Save Pattern
M Toggle Metronome

The code is given here for reference. You will need to load all the files from the .zip.

--- Code: QB64: --- '======================= 'DRUMMACHINE.BAS - v0.1c '======================= 'QB64 Drum machine 'Make drum beats using 16 drum sounds. 'Coded by Dav for QB64, MAY/2020 'Follow this programs development here: 'https://www.qb64.org/forum/index.php?topic=2459.0 '=================================================================== 'New in v0.1c... 'Added: Added program _TITLE and _ICON. 'Added: New logo with keyboard command help. 'Added: Shows big TEMPO (BMP) font at top left. 'Added: Shows green playing position line down grid. ' (replaced little white moving marker) 'Added: Give user notices when a Save/Load is done. 'Added: Instrument names can now be clicked on to mute/unmute. 'Added: Now shows on screen if metronome is ON/OFF 'Fixed: Changed keyboard input method. Much more responsive. ' '=================================================================== ''NOTE: You need "\drummachine-data\" and all of its data files! '=================================================================== '===== 'ABOUT: '===== 'This is a very basic drum machine with limited capabilities. 'With it you can program beats (limited to 2 bars of 4/4 now). 'It uses 16 real drum sounds to make a real sound drum beat. 'Drum patterns can be saved and loaded by file DRUMMACHINE.SAV. 'I just wanted to see if QB64 can handle something like this, 'and it looks like it can. So a more serious program can be tackled. 'The real drum sound samples were all found in public domain. '========== 'HOW TO USE: '========== 'The grid represents bars and notes that you can click on. 'Click on squares in a row to to add sound for that beat. 'Click an square again to turn it back off or change it's volume. 'A bright red square is loudest, a darker red is softer volume. 'Click on the instrument name on left screen to mute/unmute it. 'The following keys can be used as well: '* +/- keys: Speeds up and slow down tempo (shown upper left) '* SPACE key: Will pause and resume the playback. '* ENTER: Resets current playback marker to the beginning. '* M: Turns on/off metonome click sound (default is on) '* C: Clears the playing grid (starts over). '* L: Loads last saved grid pattern from DRUMMACHINE.SAV '* S: Saves current grid pattern to DRUMMACHINE.SAV. '* D: Enters drawing mode (fast filling of boxes. ' (While in it, enter ESC to exit drawing mode) '* ESC: Exits program. DOES NOT ATUMATICALLY SAVE ON EXIT.
