# NEC PC Engine instrument editor the PCE instrument editor contains three tabs: Sample, Wavetable and Macros. ## Sample for sample settings, see [the Sample instrument editor](sample.md). the only differences are the lack of an "Use wavetable" option, and the presence of a "Use sample" one. ## Wavetable this allows you to enable and configure the Furnace wavetable synthesizer. see [this page](wavesynth.md) for more information. note: on PC Engine, using the wave synth may result in clicking and/or phase resets. by default Furnace attempts to mitigate this problem though. ## Macros - **Volume**: volume sequence. - **Arpeggio**: pitch sequence. - **Noise**: enable noise mode. - only on channels 5 and 6. - **Waveform**: wavetable sequence. - **Panning (left)**: output level for left channel. - **Panning (right)**: output level for right channel. - **Pitch**: fine pitch. - **Phase Reset**: trigger restart of waveform.
