Title: TX81Z Waveforms
Post by: feijai on October 05, 2017, 06:01:06 PM

The Yamaha TX81Z has eight waveforms.  A few seem to be in the PreenFM2 (such as, of course, Wave 1)  But it's not entirely clear which ones are fully replicated in the PreenFM2 by default.

Given how famous and important the TX81Z is, and how common these eight waveforms are in the TX81Z and later synths, it would seem to be a very big win to have all eight of these in the PreenFM2.  Has anyone implemented these set as user waveforms?  How hard would it be to include them in the PreenFM2 by default?

I attach the first four waveforms here, and then the second four in the next message (the forum only allows four attachments per posting).  The waveforms are simply rearrangements of the quadrants of a cosine wave AFAIK.

You can use txt userwave feature in PFM2 btw. Actually i made some tx81z'alike waves with renoise sample to txt tool wich i generated with other renoise tool and they sounded pretty close to tx81z waves.
usr1.txt is tx waveform7
usr2.txt is tx wf 5
usr4.txt is tx wf 8

Rest are some random tests. Actually 5 and 6 are some voice single cycles from AKWF

I uploaded waveforms I recorded from a real TX81Z with different levels of feedback. If you’re still interested you can find them here:
