BASIC CONCEPT 4. Tone generator block 4. Tone generator block t About the tone generator block The tone generator block is what actually produces sound in response to the MIDI messages received from the sequencer block, the controller block, and from the MIDI IN connector. This is a 16part 32note polyphonic multi-timbral tone generator. t Voices "Voices" are the individual sound programs that you can edit, which are used by the tone generator to produce sound. There are two types of voices: normal voices which change their pitch as you play different notes on the keyboard, and drum voices which produce a different rhythm instrument sound for each note of the keyboard. Normal voices consist of 1 or 2 "elements." By using two elements you can produce a richer sound, or create a voice that produces different sounds depending on the pitch or velocity. Drum voices are special voices in which different sounds are assigned to each note. You can make detailed modifications to the sound of each note. Elements are the building blocks that each voice is made of, and are made from sampled waveforms. You can make detailed modifications to the pitch, tone and volume. t Bank number (MSB, LSB) and Program number (Voice number) The RM1x contains 654 normal voices and 46 drum kits. This is more voices than can be selected by a program number of 1 - 128. Thus, voices are selected on the RM1x using a combination of the Bank Number MSB, Bank Number LSB and Program Number. When using MIDI to select a voice, transmit these three MIDI messages in the order of Bank Select MSB, Bank Select LSB, and Program Change. The voices within the bank specified by the Bank Select messages are selected by Program Change messages.

The number of elements used by each voice is given in the voice lists of the separate "List Book". If MIDI messages are received which request more than the available maximum polyphony, currently-sounding notes will be turned off, and the later arrivals will be played. This type of note assignment is called "last-note priority". t Connections between the sequencer block and the tone generator block The sequencer block is internally connected to the tone generator block via MIDI. The connections between each track of the sequencer block and each part of the tone generator block can be specified by the SETUP submode Out Channel (page 75) setting "TO TG".
