Introduction
K64 Modul is seperated in 2 Applications - K64 and K2 SpeakJet Application:
K64 Application is a classic keyboard-controller to play MIDI Notes from retro C64 keyboard for
seperate UPPER- and LOWER-Keyfield Input. You can control MIDI events for specific channels too. So
you can use it as mobile input device for external syntheziser or to use it as input keys for SEQV3
application. With an additonal seperate SpeakJet Modul you are able to control parameters for
SpeakJet and SEQV3 at same time.
If a SpeakJet-Board is installed you can use the advanced functionalities "Text To Speech" Mode. This
Mode allows you to write text phrases, which are processes directly in realtime by setup variation,
speed and bend for every letter of a word/sentence. Text To Speech can be controlled via incomming
MIDI Notes in several modes. Every letter can be replaced by variations in Realtime. German
language is pre-configured.
All Text To Speech patches can be stored up to 8 external EEPROMs on a bankstick. 2048 patches
(8x32k) or 4096 patches (8x64k) are maximum possible.
Hardware
1x Core board + PIC18F452 for K64 application v2
