I have a collection of 117 Ensoniq ESQ80 waves that I'm pretty sure I dug up in the archives on the Tweaky.
Back then i used a custom Kyma Sound created with the help of SSC to convert the Original ESQ80 ROMs to 4096 samples single cycles for Kyma.
Of course this sound can be used to create just 1024 sample wide single cycles from any single cycle waveform.
It is a bit smalltalk based kyma batch sound which actually batch processes an entire folder full of single cycle waves and converts/interpolates them to 4096.
The purpose was to interpolate and smooth waves from my hardware like microwave, ensoniq ESQ or single cycles from other systems "less then 4096" samples to the 4096 Kyma uses.
I am not near my studio so i can only upload the 4096 samples version ... but you can try to change it to 1024 samples and interpolate your cycles...
All the best
