Here’s my first attempt at an 808 style cowbell:

The basic patch layout is shown below:
It is essentially 2 sawtooth waves pitched a fifth apart, but the original sound appears to have some added noise and a defined pitch envelope as well.
To recreate it with these extra features, I used LFO 1 in HF TRK mode, copying the sawtooth from DDS1 using the ‘battwave’ modification trick discussed in the manual, outputting the result on DDS1 as well. Using the LFO 1 RATE slider, this second sawtooth was tuned a 5th above DDS1. I then used DDS2 as a noise source, balancing the two sources with a MIX point at around 10 o’clock.
The pitch appears to dip slightly in the original and then gradually return to its initial state, so I set ENV1 to run in inverse mode. Adding a tiny amount of ATTACK HOLD to the transient, ENV1 self modulates both its ATTACK and RELEASE phases to make them more convex. ENV1 is then moderately applied to DDS1 and LFO1 (via the mod matrix). It is also applied gently to the MIX parameter via direct modulation to add a little more noise to the transient, and to the X-MOD to add a little pitch instability.
ENV2 features a short-ish DECAY and moderate RELEASE phase, both of which are also slightly tempered by ENV1 to be a little more convex.
The filter is set to a band pass with the HPF set to around 45%, with DRIVE set to level 1. This is then modulated by ENV1, with a initial VCF Freq around 85% of the range
The resulting sound can be heard below, without any external processing (plays B3 / key 47):
Probably needs a couple more iterations to get that sound exactly, but I can live with this one
