RE: ASR-X Pro vs. MPC2000

["Douglas Lawrence" <douglas-lawrence@home.com>]

Speaking from the specifications and not practical experience ...

The Ensoniq ASR-X Pro natively has independent dual multi-mode dynamic
digital filters (low-pass, high-pass, variable bandwidth band-pass, 
resonant
low-pass, resonant band-pass)

The Akai MPC2000 natively has a 12dB/Oct dynamic resonant lowpass filter.
But you can buy and additional ProFilter DSP card which adds dynamic
resonant multimode filter with lowpass, highpass, bandpass and
semi-parametric EQ response modes.

>From what I've heard, the filters on the Ensoniq seem more dramatic than 
>the
Akai. But if that's what you into, the Yamaha A3000 or Emu ESI-4000 have
even more/better filter sections.

For comparison ...

The Yamaha A3000 has HPF, LPF with resonance, BPF, BEF).

The Emu ESI-4000 has 6-pole filters (18 different types)

The new AKAI S5000/S6000 samplers will have *all* these types of filters 
...

4-Pole Lowpass - A lowpass filter with a 24dB/Octave rolloff and variable
resonance.

4-Pole Bandpass - A bandpass filter with 12dB/Octave rolloff either side of
the passband and variable resonance.

2-Pole Highpass - A highpass filter with 12dB/Octave rolloff and variable
resonance.

2-Pole Lowpass - A lowpass filter with a 12dB/Octave rolloff and variable
resonance.

2-Pole Bandpass - A bandpass filter with 6dB/Octave rolloff either side of
the passband and variable resonance.

1-Pole Highpass - A highpass filter with a 6dB/Octave rolloff and variable
resonance.

Notch - A simple notch filter. Resonance affects the width and depth of the
notch.

Dual Notch 1 - A filter with two notches spaced an octave apart. The effect
is similar to phasing. Resonance affects the width and depth of the 
notches.

Dual Notch 2 - A filter with two notches spaced two octaves apart. 
Resonance
sets the width and depth of the notches.

Peak Filter - An EQ type filter with variable boost.

Dual Peak 1 - A sweepable dual formant filter with two peaks spaced an
octave apart.

Dual Peak 2 - A sweepable dual formant filter with two peaks spaced two
octaves apart.

'HaLo' Filter - A combination of highpass and lowpass filters which are
lowpass at the lower end of the frequency spectrum and highpass at the 
upper
end.

'PeakoLo' Filter - A 12dB/Octave lowpass filter but with exaggerated
resonance. 'Voweliser' Filter Creates vocal effects.

Are there filters in the MPC 2000 ? If so , what are they like?
