The SK1 is known in the circuit bending world as being one of the most interesting and diverse instruments available for modification. There are so many possible modifications, that a patch bay is commonly added, which allows the user to manually make thousands of different patching combinations. The patches can range from very simple to extremely complex depending on how deeply the user wishes to explore.

<h3>There are a few standard features that I add to every SK1 I modify.</h3>
<ul>
<li><strong>Approx. 20 point patch bay.</strong> - An astonishing diversity of effects can be created by patching points together in 
different configurations. <a href="/images/finishedpieces/casper-sk-1/sk1_patchpoints.jpg" rel="lightbox">View a large patching points diagram.</a></li> 
<li><strong>Patchable adjustments</strong> - One of the weaknesses of the simple patch bay is that effects can only be turned on or off, there's no subtlety to it. By patching the points through a potentiometer, the amount of signal passing between these points can be adjusted. This allows the user to subtly transform certain effects and drastically increases the amount of control one has over the sounds being created.</li>
<li><strong>Timer module and timer input patch points</strong> - The SK1 has a feature that lets you record and playback sequences of notes. The sequence can be played back as one string of notes by pressing the "auto play" button, or it can be played one step of the sequence at a time by pressing either of the two "one key play" buttons. The timer basically sends a rhythmic trigger signal to the "one key play" feature. So once you have recorded a melody into the SK1, the timer will play back the sequence of notes, leaving you free to experiment with different patch point connections. The timer is a separate circuit which can be built into the housing of the SK1 or into its own separate container. The rate can be adjusted from several pulses/second to several seconds/pulse.</li>
</ul>
