 Wavetable synthizers, in context of Furnace, are sound sources that operate on extremely short n-bit PCM streams. By extremely short, no more than 256 bytes. This amount of space is nowhere near enough to store an actual sampled sound, it allows certain amount of freedom to define a waveform shape. As of Furnace 0.5.8, wavetable editor affects PC Engine, WonderSwan and channel 3 of Game Boy.
 
-Furnace's wavetable editor is rather simple, you can draw the waveform using mouse or by pasting an MML bit stream in the input field. Maximum wave width (length) is 256 bytes, and maximum wave height (depth) is 256. NOTE: Game Boy, PCE and WonderSwan can handle max 32 byte waveforms, X1-010 can handle max 128 byte waveforms as of now, with 16-level height for GB, X1-010 Envelope and WS, and 32-level height for PCE. If larger wave will be defined for these systems, it will be squashed to fit within the constraints of the system.

+# Bubble System/K005289
+
+a Konami's 2 channel wavetable sound generator logic used at their arcade hardware Bubble System.
+
+It's configured with K005289, 4 bit PROM and DAC.
+
+Also known as K005289, but that's just part of the logic used for pitch and wavetable ROM address. Waveform select and Volume control are tied with AY-3-8910 port.
+
+furnace emulates this configurations as single system, waveform format is 15 level and 32 width.
