Use this mode when you want to edit the internal sounds or MFX in greater detail. Although this mode lets you control parameters that cannot be edited in other modes, operations in Native mode are not compatible with GM2. In other words, song data created in Native mode cannot be reproduced by playing it back on another GM2 sound generator. PART 1 PART 32 Instrument Parameters Part Parameters MFX A MFX B MFX C DRY OUT MFX OUT Instrument Parameters Part Parameters MFX Parameter 3 MFX Parameter 2 MFX Parameter 1 Parameter reference Signal Flow • In Native mode, MFX and sounds (instruments) can be handled independently. For this reason, simply selecting an Enhanced sound will not automatically cause MFX to be applied. You will need to edit the part parameters in order to apply MFX. • You can also apply effects to sounds other than the Enhanced set, or input the signals from multiple parts into a single MFX. * For details on using MFX, refer to “Verwendung der Effekte des internen Soundgenerators” (p. 41). Controlling theSD-80 via 57 Controlling the SD-80 via MIDI • A greater number of the Part parameters can be edited from the SD-80. • When creating song data, you can select sounds from the Classical/Contemporary/Solo/Enhanced sound sets simply by specifying the Bank MSB/LSB and Program Number. • You can use system exclusive messages to control the Patch parameters that create the sound; e.g., pitch, TVF (filter), LFO, and envelope. * For details on the parameters, refer to “Each Multi-Effects Parameters” (MFX_E.pdf) on the included CD-ROM. • These sounds are selected individually for each of the 32 parts. Unlike the Part parameters, the sound (instrument) parameters belong to the sound (not to the Part), meaning that their settings will be overwritten by the newly selected sound when you switch sounds from the front panel or by using program change messages. (The Part parameters will remain as they were set.) If you want to use sound parameters within your song data, you must select the sound before you modify the parameters. Specify the sound A parameters Transmit a program change and part parameters at the number during the song to beginning of the song switch to sound B Part parameters Song data (time) Sound A parameters Part parameters Sound B parameters The structure of the synthesizer When controlling the sound parameters, it is important to understand the structure of a conventional music synthesizer (oscillator, TVF, TVA, envelope, LFO). We recommend that you understand the following concepts before you use the operations described in this section. WAVE LFO Provides for selection of the PCM waveform (wave) that is to form the basis of the sound, and specifies how its pitch will change. TVF (Time Variant Filter) Determines how the frequency components of the sound will change. Pitch TVF TVA TVA (Time Variant Amplifier) envelope envelope envelope Specifies how the volume will change, and set the stereo position. Control signal Envelope Audio signal Specifies how change will occur over time. For example if you want to adjust the time over which the sound attacks or decays, you would adjust the TVA envelope to specify the desired volume changes. LFO (Low Frequency Oscillator) Specifies cyclic change (modulation). You can create vibrato by applying LFO to the pitch, “wah” by applying LFO to the TVF cutoff frequency, or tremolo by applying LFO to the TVA volume. filter (TVF) level (TVA) oscillator (WAVE) Controlling the SD-80 via MIDI Switching the sound set GM2 mode and Native mode each have four sound sets (variations). You can use MIDI messages to switch between these sound sets. Switching the sound set in GM2 mode In GM2 mode, you can switch the sound set by transmitting a system exclusive message.
