I used to own a blue Roland SH-101 with the cool modulation handle and shoulder strap. These days I use the Powercore01 which is a SH-101 emulation. There is a new free emulation for Mac and PC called TAL-Bassline. Not much more say here because this one is totally free so go an try it yourself! Here’s the details:

• VST Mac (Universal) and PC
• Band-limited oscillators (saw, pulse)
• Sub-oscillator: square -1 oct., square -2 oct., pulse -1 oct, pulse -2 oct
• -18 dB/octave low-pass filter (resonant/self-oscillating)
• LFO (frequency: 0,1 .. 30 Hz, waveforms: sin, tri, saw, rec, noise)
• Very fast nonlinear envelope (A: 1.5ms..4s, D: 2ms..10s, S: 0..100%, R: 2ms..10s)
• Simple Arpeggiator (up, down, one octave mode)
• 2x Unisono Mode
• Panic button
• MIDI automation for all sliders and pots
• Precise fader control while holding down the “Shift” button
• Supports all sample-rates
• 2x oversampling
• 23 presets
• Tutorial PDF
• ~2.5% CPU (Intel Core 2 CPU 6700, 44.1KHz, 24Bit, buffer-size 1024 Samples
