Re: [emulatorII-list] Do you realize the EII also has a 2 pole filter?

<div id="ygrp-text"><p>So tonight I'm looking at the filter schematics trying to determine why the resonance on one of my voices has a higher Q than the others... and noticed that the SSM2045 filter chip has both 2 pole and 4 pole outputs!<br>
Since there is just a single 4.7K resistor connecting the output of the 4 pole filter to the input of the amplifier, it seems quite simple that one could remove this 4.7K resistor, run wires from the 2 and 4 pole outputs each to seperate 4.7K resistors which are then connected to the two positions of a toggle switch, the switch common connection then routed to the input of the amplifier. <br>
Add this stage for each of the eight voices, and then mount the toggle switches just above each voices output jack. <br>
<br>
I think this could create some interesting results. Being able to play both 12db and 24db filter types at the same time. Or creating rhythmic filter type changes as individual notes rotate through the voice assignments. Plus in my opinion with these SSM and CEM chips the resonance seems to sound better on 2 pole settings. <br>
<br>
There is also the ability to use the unused portion of the SSM2045 to create a high pass filter as well, although adding this mod would most likely be a bit more complicated. <br>
<br>
Well I for one am at least going to try seeing what the 2 pole filters sound like.<br>
<br>
By the way, has anyone ever used their EII as a stereo sampler?<br>
Taking individual left/right samples assigning them to the same key ranges, but sending them to say left/voice 1, and right/voice 2.<br>
