| Curtis CEM 3387 filter chip as used in the Waldorf Rev.B microWaves and WAVEs. No bass reduction with higher resonance settings. | Discrete ladder filter based on CA3046 transistor arrays (5 very good matched transistors in a single 14 pin chip) as used in the Waldorf Pulse. Typical loss of bass with higher resonance settings. | |

| The CEM 3387 filter chip is positioned between the two pairs of 1/4" sockets. Maxim MAX500 quad 8 bit DAC to generate the control voltages for Cutoff, Resonance, VCA and Panning. This ship is here (later?) exchanged for the SMD version. Other 4poles got the bigger through hole version. | Three CA3046 transistor array chips are positioned between the two pairs of 1/4" sockets. | |
| The also differ in the firmware used. The parameters like envelope timing do not match. So programmes saved on one version will not sound alike on the other version if the data is exported by sysex or by using the very same parameter values shown in the display. | ||
| Remark: The position where the bigger blue button is placed is not depending on the version. They were often accidentally changed when the 4pole was opened. | ||
