Bastl Instruments - Spa (Alu)

Spa is an expander for the granular sampler module grandPa from Bastl Instruments. It adds CV inputs for nearly all parameters and a clock input to trigger grain shift. It doesn’t work without the grandPa Eurorack module.

Features:

• independent CV inputs for most parameters of the grandPa module
• CV inputs with attenuators are normalised to 5V so the attenuators work as direct controls of the parameters for both channels A and B of the grandPa
• CV inputs react only to positive voltages from 0-12V
• Grain Size and Shift Speed CV inputs with attenuators
• switch to select whether the other two CV inputs with attenuators control Start / End or Attack / Release parameters
• Crush CV input
• Grain Sync input to trigger grain shift
