very nice sounding filter btw, IMO, apart from the other interesting features..
nice work CableGuys

Peace out and happy easter, Jakob

I just tested with the current demo of Renoise. So..: Other than with other hosts, in Renoise the song needs to be running to have the wave display updated.

Let me know if this solves the problem.

The next Alpha is online, Alpha 6:

The old 24dB-LP filter is named 24dB-LP2 now and we added new 24dB-LP/HP/BP filters. We are unsure, though, if the LP2 should make it in the final release. It has a nice, own character, but sounds different for different sampling frequencies. Any opinions on that are very appreciated.

Hi Jakob,

I am testing this at the moment and I'm really impressed with it but I cannot find the parameters for the 2 buttons that flip / invert the waveform (both vertically and horizontally) in the list of automatable parameters..

I also cannot find a way in Cubase 5 to change the effect presets quickly and easily - it would be great if this was automatable as well. This is for quickly switching from one patch to another. For example, I would like to switch the filter effect patch on my break / bass from say the presets 'Bandstop' to 'Acid' to 'The Pendular' as the song progresses.

I've double checked the options in the automation lane, but there no parameter for changing the actual preset? (but I can see a list of many other modulation destinations)

I've tried clicking the 'R' and 'W' buttons then clicking the Record button, then whilst recording, flicking through the presets - but when I playback with 'R' enabled the presets don't change.

I've tried inserting MIDI Program Changes (PrgChg) messages on a newly created separate MIDI channel which is routed to the insert Filter Effect.

I've tried using Filterscape as a send effect rather than an insert and routing program change MIDI messages to that via a MIDIYoke virtual MIDI cable.

I'm probably doing it wrong but the plugin does not seem respond to any of these methods. The workaround which is to create many multiple of lines of automation to change individual parameters (cutoff/res/lfo rate etc) to achieve the same effect each time you want to switch patches is not really a practical solution .

Maybe it is just me - does Filterscape effect respond to PrgChg messages on other peoples computers? If not, can automation functionality or MIDI Learn be added for these missing parameters?

Any advice is very welcome - thanks!

Ah the old FilterShaper 1 thread.. quite some memories this picture on page 1 brings on.

The button is not a parameter. Instead, clicking on it influences other parameters (here: changing x and y values of the points, which are parameters). Clicking on it changes these parameters, and that can be recorded by the host sequencer.

No idea how Cubase handles program changes, if that's automatable. But I propose that you take 3 instances of FilterShaper with different patches, and only activate the FilterShaper instance that you need (I guess Cubase allows to automate the on/off-state of a plugin?).

Hi Jakob, thanks for taking the time to reply

In my confused mind I was thinking that these two buttons could each be a parameter themselves. Thanks for explaining - I'll give this a try.

Thanks for your suggestion on this point: for making dnb and dubstep I would really like to switch between more than 3 preset filter settings per song - it's more like 33. I originally mentioned just 3 presets because it made my example clearer to understand. For me it is not really practical to create 33 instances of Filtershaper, solo one and mute the other 32 whenever I want to switch the filter effect preset, which may be a large number of times, per song. I was curious because many (most?) VST Instruments respond to MIDI Program Change messages so I wondered if / why this was not possible with Filterscape. Maybe it's all VST FX in general? It would certainly make programming filter switch-ups a lot easier - a feature which could be very useful with today's musical styles. In the meantime I have thought of a workaround which should be a lot neater than repeatedly solo-ing 1 / bypassing multiple FX channels but it's still not as straightforward or CPU-efficient as sending a MIDI PrgChg message.

All the Best,

djskope

Got it. I'll write down MIDI PrgChg message as feature wish. Wondering though, if the host sequencer can send this PrgChang message dedicated to FilterShaper - so if there are other effect plugins or a synthesizer on the same track, how do we know that the PrgChange is dedicated to us.

But besides that, all parameters can be automated. So you can have different waveforms in FilterShaper's 10 waveform slots and automate the LFO's waveform selection, to have different waveforms in different parts of your song. You can also automate LFO frequency, LFO mode, filter parameters, or waveform points. Not as neat as switching between presets for your purpose, but maybe it helps.

Good question - In Cubase I'm pretty sure it can be done by using Filtershaper as a send effect and routing the MIDI to that, and maybe even when using FS as an insert effect. I'm in the middle of Belkin KVM hell today but once I get that sorted I'll test and post a routing screenshot.

By the way my thoughts for a workaround for using MIDI to control switching is to use one of Soma's excellent switchers (there is a 4 and a 12 channel version I think) combined with Energy XT. The fantastic, modular Energy XT can then be loaded as a VST in Cubase with this patch. Disclaimer - in principle this should also work with Filterscape, or any VST effect but I haven't tested it out on FX yet

Replace Massive with instances of Filtershaper in the screenshot above. Then (in theory) you can control which instance of Filtershaper is activated (exclusively soloed) by CC2(?). Soma's is pretty cool - there is even a CC for glide time. More about this workaround at http://www.kvraudio.com/forum/viewtopic ... highlight=

Hi Jakob,

Well I have searched and I couldn't find anything specifically on using *Program Changes* to change presets for VST *Effects*. Also I was wrong about being able to simply add a blank midi track and change the output to point to whichever effect plugin you wanted (that's in Cubase - other 'newer' DAWS may already support this via MIDI Learn etc). I tried both insert and send methods but no success. Seems like this is an oversight which IMHO should have been been included as a default feature of the VST spec by Steinberg.

However, I did find some useful info on how to enable a VST effect to receive MIDI (CC's?).

http://www.kvraudio.com/forum/viewtopic.php?t=312502
(the code posts by arakula and yeahtuna about 1/4 down the page)

http://www.kvraudio.com/forum/viewtopic.php?t=64671
(the post by Crandall1 at the bottom of the page)

Once the effect plugin has been given the ability to accept incoming MIDI the next question is whether or not incoming Program Change messages can be internally converted to Preset Change message. Unfortunately I sailed into uncharted waters here and couldn't find any specific info on this. But not being a coder I haven't even read the VST SDK so this possiblity may be exist - I just don't know about it.

A real world example of an effect which shows up as a MIDI-Input enabled effect even in Cubase is LFOTool. With it you can use MIDI Notes to Change graphs via MIDI notes or Retrigger, Gate & Change Rate.

I do realise that this can all be done via Automation but I personally find that method a pain - MIDI editing is years more mature, simple and easily edited.

I'll carry on with my workaround for now. Hope the info above helps some - let me know if you need any beta-testing.

All the Best

Thanks djskope for all your research here. For let's see if more users request this. All busy with Curve 2. But FilterShaper 3 is also in the making.

Both VolumeShaper 3 and MidiShaper are VST effects with MIDI input btw. We are using this to trigger the LFO(s) and envelopes.

Thanks for adding this to the wish list Jacob and good luck with the launch of Curve 2

For now I can confirm that the workaround for automatic CC crossfading between effects as per the screenshot above works in Cubase with Filtershaper within EXT so I'm a happy bunny this morning!
