Hier noch etwas vom Herrn Behringer zum Thema Filter des MS101:
Zitat:Which filter is used in the MS101
Some people have asked what filter type has been used in the MS 101 synth since the original IR3109 filter chip is no longer available.
We first considered creating a replica of the original 3109 chip, like we’ve done with the 3340 and 3320 Curtis chips.
However we discovered alternative circuitries which you can find here:

Having done detailed measurements and sound evaluations of various circuitries, we came to the conclusion, that one particular solution stood out and delivered nearly identical sound results when comparing it to the original chip.
It’s important to understand that even analog chips do have tolerances and hence no two chips will sound identical, let alone comparing two analog synths with their huge amount of components.
Since Coolaudio is our chip provider, we decided to select and match our V13700 OTA’s to get even closer to the original tolerances.
Based on these findings, we decided that there was no need to redesign the original chip and hence we employed the best of these available discreet solutions and matching components.
