Hello Christoff,
Christoff wrote:Thanks for your reply. Perhaps I haven't explained very well. The Midi files do play perfectly - identical to the live performance. The problem is with the audio/wav file Hauptwerk has made whilst the Midi file is playing. There is a marked diminution in the volume of the swell which is not present on the Midi file. I think you might be right that it is something to do with the recording of the swell pedal position. I have watched the swell pedal indicator and this stays in the fully open position at the point where the playing on the swell decreases sharply on the audio/wav file.
I have re-recorded a couple of times and the same problem occurs at exactly the same point.
I wonder whether perhaps your MIDI console is periodically sending occasional MIDI messages to Hauptwerk that's unintentionally affecting something (e.g. an expression pedal). The fact that it occurs at exactly the same point makes that seem relatively unlikely, but it's definitely worth checking anyway:
If your MIDI console is connected to the computer using physical traditional MIDI leads, then please try disconnecting all of those leads temporarily, and also turning off the power to the console completely (in case the console is somehow affecting an amplifier level or something similar). Does the MIDI file then play back properly in Hauptwerk?
If not, or if your MIDI console is instead connected via direct USB leads, then exit Hauptwerk, temporarily disconnect all MIDI/USB leads from the computer, turn the console off, and launch Hauptwerk via a previously-unused 'Hauptwerk (alt config N)' desktop short-cut. Those separate configurations (desktop short-cuts) have completely independent settings, so the intention is to eliminate any possibility of a non-default setting affecting something. When the wizards run upon launch, don't enable/tick any MIDI ports at all, and select just a single stereo audio output on your audio interface (its ASIO driver, if Windows), so as to try to eliminate any possibility of issues relating to separate amplifiers with multi-channel output, and to try to eliminate any possibility of issues relating to VST/AU/effects, etc.. Load the Salisbury and play back the MIDI file. Does it then play back properly?

I know that this recorder can sometimes suffer from very large impulses, much higher amplitude
than the normal recording level (which is sampleset dependent). I have no idea what causes
the impulses.
Can you use an audio editor to look at the recorded waveform at the point where the problem
occurs? You may see a large very brief pulse or if not you may see some other obvious
imperfection.
Hello csw900,
I can assure you there are absolutely no known faults in Hauptwerk's audio recorder, and it's been used very intensively by a lot of people for many years, so I'm pretty sure we'd have heard about (and would thus have rectified) any that might have existed.
If you decide to buy a licence for Hauptwerk in the future, then we can look into this for you. (I already spent quite a number of hours looking into a previous issue for you, which you mistakenly thought was as a bug in Hauptwerk, and we do have to make a living -- sorry!)
Best regards, Martin.
