XW P1 Filters

[CairnsFella]

Hi all.

 

Last night I re-watched a Casio Workshop (synthesis 101) which used a P1 and a PX5. In that tutorial it stated that the XW's only have a total filter on the solo synth. Withough yet owning the P1 I cannot check this first hand but this was also what I had previously believed.

 

However, looking at the P1 manual on page E-22 (editable solo synth tone parameters) it clearly shows a separate filter in each of the six oscillator/sound/noise blocks. Is the manual plain wrong, or is my was my original understanding and the workshop video incorrect?

Take a look at the PDF I uploaded to your block diagram thread.

There are many filters, or at least cutoff parameters available, with the XWs; but only the solo synth total filter is resonant. The filters within each solo synth block, PCM tones, hex layers, user waves, etc., are all non-resonant.

OK. Thanks for the info. A bit for me to look into here, much appreciated.

 

Based on your info I looked at the workshop again and it definitely highlights that the (a) difference between the PX5 and XW is that the PX5 has it's own filter on each of its layers. Now knowing the limited amount that I do about the XW, one could obviously interpret what is being said to mean the difference between the 'hex layer filtering' specifically on the XW and the PX5. However the fact is that the video compares the solo synth layers on the XW with the hex on the PX5 (and shows signal paths for each in turn... around 33.19) and says that the XW only has the total filter and the PX5 has its it's own filter on each of the layers. Resonance - in this part of the video - is not a factor. So I would consider that information to be a little misleading.

 

It would probably be fairer to suggest that the two different tone generation methods (solo and hex) should not really have been compared in the same breath, or at least should have mentioned that these were quite different elements.

 

Anyway, its not a problem (nor a complaint of the XW's limitations, as the fact is I didn't realise there were independent non-resonant filters on the XW solo synth), but just an observation that it confused me.

 

Thanks again for the info.

Where the P1 differs to the G1, is that unlike the G1, the P1 has some restrictions on the use of the resonant filter. The G1 can route any of its sources through the solo synth filter (PCM sounds, solo synth, samples, step sequencer etc.) The P1 meanwhile CANNOT route the HEX Layers or the Drawbar auction through the solo synth resonant filter as these sections are exclusive. You can use the "Wah" DSP to get close to a filter effect, and I think you can add a non resonant filter via the Mixer section (others will confirm how to get a similar effect when in Hex or Drawbar mode).

 

You can check the little guide I wrote with regards to using the solo synth filter outside of the solo synth mode:

Chas.

Thanks. I have read your guide previously. Very helpful. Although I will probably commit more to memory once I actually have an XW to hand.

Having said that, my point here was clarification of what was being said with regard to separate filters in the solo synth oscillators. I feel that I have now established the workshop was at best 'misleading' or at worst 'wrong'. Having said that, I am now happy that I understand the facts in this regard.

Thanks again.
