# Namco 163 instrument editor the Namco 163 instrument editor consists of three tabs: "Namco 163" for control of various waveform parameters, "Wavetable" for control of the wave synth and "Macro" containing several macros. ## Namco 163 - **Load waveform**: if enabled, a waveform will be loaded when this instrument plays. - if it isn't then only the position/length change. - **Waveform**: determines the waveform that will be loaded. - only appears when Load waveform is enabled. - **Per-channel wave position/length**: when enabled, the position/length settings are split per channel. - **Position**: determines the waveform position in RAM. - **Length**: determines the waveform length in RAM. ## Wavetable this allows you to enable and configure the Furnace wavetable synthesizer. see [this page](wavesynth.md) for more information. note that setting the Update Rate to something greater than 1 and playing the instrument in two channels may result in conflicts. ## Macros - **Volume**: volume levels sequence. - **Arpeggio**: pitch sequence. - **Wave Pos**: sets waveform seek position in RAM. - **Waveform**: sets waveform. - **Pitch**: fine pitch. - **Wave Length**: sets waveform length.
