Random Arpeggios
The A-148 can be used in conjunction with a module such as the Doepfer A-118 to create random voltages from the A-118's random output. An LFO triggers the S&H module, so that with every oscillation of the LFO, a new random voltage is output to your VCO's CV input. If you patch an A-130 VCA in before the VCO, you can adjust the Gain and Out amounts to restrict the frequency range of the random voltages to whatever you desire. You can also use a similar setup, but patch the S&H voltage output to the CV input of a filter set to high resonance to produce a variety of interesting rhythmic timbral changes.
Glisando
If the CV output from a keyboard is patched into the Doepfer A-170 Slew Limiter, the A-148 can be triggered by the rising edge of an LFO, which samples the output from the slew limiter, and produces a staircase voltage which controls the pitch of a VCO. With this configuration, playing two notes, particularly ones that are spaced widely apart, produces an interesting glissando effect.
Each S&H sub-module/section features the same I/O configuration.
