Topic: H. Ruckers II, coupling upper to lower

I use two manuals (like a real harpsichord) to control the H. Ruckers II plugin. For this to work I need to use two instances of the plugin in my VST Host. This raises a  question related to coupling the upper to the lower keyboard.

Is there a difference in sound when activating U8' and L8' in one plugin, compared with activating U8' in one plugin and L8' in the second plugin?

Thanks for listening
Michael

I suspect there will be a difference in sympathetic resonances, since if everything is running in one Pianoteq instance, it "knows" about everything, whereas if it is in two separate instances I don't think they can "talk" to each other.

This raises the question:

My understanding is that Pianoteq allows you to control a lot of MIDI settings and you may be able to use a single instance for this setup -- however that's not something that I do or have experience with, so I may be wrong with this opinion

Thanks for your reply.

Yes, in the MIDI tab you may define your own MIDI mappings responding to Channel Events or MMC. Then there is the "Notes Channel" dropdown, and I read about "multichannel MIDI layout", which seems to support the creation of instruments that require more than 128 notes.

I can't see how I could use this parameter for my problem. I need two channels that can be routed to different Harpsichord patches.

BTW I'm using Pianoteq Stage. I noticed that Pianoteq Standard supports "instrument morphing an layering". Will this do the job for me?

Ah, I see, you need to use two completely different "instruments", correct?
In such a case, I am not sure if the resonances would be shared among them. I mean, in real life they do (e.g. when my daughter plays clarinet, my acoustic piano resonates quite noticeably if I have the pedal down), but I am not sure how pianoteq would behave in such a situation.

Perhaps layering would do it. The good news is that Pianoteq is really king of user friendliness: you can install as many versions as you please, side by side, licensed or demo. Take advantage of that: download the Pianoteq Standard Demo, give it a try and see how it behaves. Besides the missing keys (and time limitation) is fully functional and its installation will not change anything on your Pianoteq Stage licensed one.

The first test I would do is to simply do a layered split of a single keyboard: lower part using one instrument and upper part using another. See if the resonances are shared from one to the other. If not, everything else is a moot point. If so, you'd have to figure out how to route the midi from the two manuals to the two separate instruments. I'm sure you can do it, and there may be more than one way to accomplish that.

Best of luck!

Not really, it is a single instrument with two manuals and - in the case of this Ruckers harpsichord - is equipped with three independent set of strings which may or may not be combined.

I would be surprised if resonances between two totally different instruments are implemented. A dedicated input would be nesessary much like a side-chain in a compressor.

While there is no sustain pedal at a harpsichord there surely exist resonating effects for those strings with their keys depressed.

As you suggested I will install the demo Standard version to see if I can attach to manuals to the plugin of separate MIDI channels. It should be easy to detect if the plugin has string resonance implemented.

Just thought some had done this already or some Modartt employee chimes in.

Thanks again.
