Instrument
Moka
Stereo modal synth for struck objects — xylophone, glockenspiel, woodblock, glass bowl, metal sheet, and tube — with ten controls and ten factory presets.
Opinion
The most playable struck-object voice in the set. Metal Sheet into a long Decay is an instant thunder plate; Glass Bowl with soft Mallet sits under pads without fighting them.
Functionality
Moka renders each note as a bank of eight damped sine modes excited by a short mallet transient. Six instrument tables (Xylophone, Glockenspiel, Woodblock, Glass Bowl, Metal Sheet, Tube) set the partial ratios, levels, and decay multipliers; the ten panel controls then morph excitation, resonance, ring-out, and stereo spread around that table.
