JITT64

JITT64 (Java Ice Team Tracker) is a tool for creating music with the SID chip used into the Commodore 64.

This tracker is for making music without using low rastertime, but instead gives you a possibility to make very complex instrument definition. You have freedom in creating your music!

Each instruments (max 255) are based onto tables and one instrument can takes up to 2KB of data without sharing the definition with other instruments.

Not used features are removed when compiling the player to improve rastertime usage (it is possible to use undocumented opcode too).

Activate the below webgl music player to listen to some example tunes:

JITT64 has various themes to use, so even the look can follow your stile!

Beta 1.05 has:

• Option: fix initialization of zero page vs useopcode
  
• Option: add command portamento over relative freq. of instrument behavior
• Option: use direct D404 output for Gate/Sustain Release command
• Option: use Matt Gray digi
• Option: use new track format
• Pattern: allow min time to 1 from 3
• Pattern: allow min dimension to 1 from 2
• Pattern: allow man dimension to 999 from 255 (with 255 previously it gives sound errors), but you could compile JITT64 to support up to all C64 memory
• Pattern: detune up/dn commands
• Pattern: can go to 252 instead of 222
• Track: allow man dimension to 999 from 255, but you could compile JITT64 to support up to all C64 memory. Now a repeat can be set only inside 255 interval and if you make it with tune that has more than 255 interval the restart point must be in a pattern to avoid instrument restart problem
• Track: real time playing now is Swing thread safe (optimal visualization)
• Track: new format with 252 pattern and transposition of -64..64 semitones
• Song: allow to import Music Assembler/Voicetracker tune even from PSID file
• Song: allow to import Music Mixer tune even from PSID file
• Song: allow to import ElectroSound tune from PSID file
• Song: allow to import Soundmaster tune from PSID file
• Instrument: fix rel note indipendence in instrument and render in table
• Player: fix gate off on last tick
• Player: fix simulate next pattern with rep command crash
• Player: activate command portamento over relative freq. of instrument behavior
• Player: activate use direct D404 output for Gate/Sustain Release command
• Player: support big pattern dimension (999)
• Player: support big track dimension (999)
• Player: support Matt Gray digi
• Player: support new track format

• Option: can set the number of undo action
• Option: can set if input text after popup of instrument should be erased after input action
• Option: add 468Hz A4 freq. table (Paul Hugles), 415Hz table (Prosonix Editor), 438Hz table (Goattracker1 Editor), 449Hz table (Ian Crabtree) and fix invalid 434Hz table.
• Option: can use undocument opcode in player
• Player: can have user comment
• Player: conditional compilation to remove commands in pattern not used
• Player: mute instrument execution at finish of song and during rest command
