Paul<p>7/ It was the nuvistor. It’s always the f$&king nuvistor. Both autoranging plug-ins are somewhat working.<br>Vertical plug-in still has some ranging issues, and the horizontal plug-in is slow to un-blank, which becomes a problem at higher sweep speeds. I’ll tackle that next. <br><a href="https://oldbytes.space/tags/retroTech" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retroTech</span></a> <a href="https://oldbytes.space/tags/vintageTech" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>vintageTech</span></a> <a href="https://oldbytes.space/tags/tektronix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>tektronix</span></a> <a href="https://oldbytes.space/tags/1960s" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>1960s</span></a> <a href="https://oldbytes.space/tags/testEquipment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>testEquipment</span></a> <a href="https://oldbytes.space/tags/electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>electronics</span></a></p>

stevenray<p>This is a music studio equipment appreciation post.</p><p>I've been acquiring old 1970s test equipment lately, stuff that was never intended to be used to make music (I blame Hainbach, look him up on YouTube).</p><p>I recently got a pulse generator (the unit on the right). Syncing it to the function generator on the left gave me a way to create these gritty, punchy lofi non-standard rhythms. You might call them glitchy. </p><p>They sound so good.
