Envelope weirdness when Decay and/or Release are at their minimum.

[Computer Controlled]

Just got my Microbrute this evening.  Set it up via the SW to clock the sequencer via the Gate Input.  I expect this to behave the same way as the SH-101's sequencer.  It does, however, when i set either the Decay or the Release parameters to their minimum settings, they gate on certain steps.  This is odd behavior.  They should just click away, but instead, on certain steps, they sustain.  Is there any reason they do this?  I have to be very careful when setting Release almost to zero.  I'll make a video to show you what i mean, but for now, i hope you understand =o]  I haven't tried to do this via MIDI yet, as i'd rather use the sequencer the way i did when i had an SH-101.

Here is a short video i just did.

As you can see, it's a bit odd behavior.

NM, i figured the problem out.   I am using a sampled trigger pulse from my old TR-707 via an Octatrack, i had a Filter effect engaged on that sample channel, and it was causing the odd behavior.  I put no effects on the sample, and it behaves properly.
