      Red Panda’s Tensor is full of unique effects: deep, sensitive, interactive controls.  The RAND parameter alone is worth the price of admission.  But I’m finding many of these effects can be recreated in the H9 & TimeFactor algorithms.  Here is one of the standard FX featured in the Tensor:

      SPEED set to -100% (reverse).  BLEND to 100% wet.  TIME, PITCH, and RAND to neutral positions.  The HOLD & DIR toggle settings are inactive.  The ON switch is switched to MOMENTARY.  Tapping or holding the ON footswitch instantly rewinds what you’ve just played (reversing the contents of the 2.4 second record buffer).  Here’s the equivalent preset in the H9/TimeFactor Reverse algorithm:

      FULL HEEL – AUX OFF POSITION

      To get the momentary action, it’d be best to connect at least one Aux switch to the H9.  It’s possible to bind the Aux switch to Parameter 1 (algorithm-dependent – usually the MIX parameter).  I prefer the Aux switch controlling the Expression Pedal parameter.  Easy to program & tweak, savable per-preset, with the potential for control over multiple parameters simultaneously.

      FULL TOE – AUX ON POSITION

      When you tap the Aux switch, your phrasing is immediately played back in reverse.  It’s always recording in the background, up to the 2400 mS limits set in DELAY A & DELAY B.  The 100 mS XFADE seemed like an accurate compromise, and I left the remaining controls at neutral values.  You won’t get the “tape stop” drift at the end of the delay buffer, like the micro-effect you’d find with the Tensor.

      50:50 MIX VARIATION

      If you’d prefer to eliminate the top-tapping, the preset above is close to a 12:00 BLEND position in the Tensor.  The H9’s static WET MIX value will mimic the Tensor’s ON switch, toggled to LATCH.

      One Tensor preset variation sets the ON & HOLD switches to LATCH, and uses the HOLD – REC and DIR – FWD 3-way toggles.  The idea is to tap HOLD to record the reverse audio into the buffer, then have it play back automatically when that buffer is full.

      The REPEAT function in the TimeFactor / H9 will almost get you there (there’s a 5.8 second maximum buffer in the Tensor).  But it’s a feature available within every TimeFactor delay preset.  No need for finger toggling or external MIDI.

      100% WET MIX will be normalized to always-on, rewinding phrases.  Map the Aux switch (or a 2nd Aux) to the Performance / Repeat function.  Here, REPEAT ON captures the last 2400 mS in the record buffer, and plays it back (reversed) in a continuous loop.  REPEAT OFF drops that loop, and slides back into live input being rewound.  To get to the 5.8 second buffer size in the Tensor, you’d have to turn to the Looper algorithm, or possibly FILTER PONG.

      I probably needed to link the Preset Sharing downloads, at some point:

      TENS REV NO HOLD (post above)

      TENS REC FWD REV (post that follows)

      https://www.eventideaudio.com/community/presets/brock/tens-rec-fwd-rev 

      Another nice Tensor configuration uses the 5.8 second buffer as an infinite background loop.  The twist: the loop will play forward, then alternate to reverse playback.  Latch the initial recording to create the loop, autoplay back, and glide between forward & reverse.  Latching HOLD again will replace the recording with a new loop.  The record buffer will vary in length (between HOLD taps).

      In the H9 / TimeFactor version, you’ll have to get creative for the alternating FWD / REV playback.  At least two ways to do it:  Binding an Aux switch to the PLAY button will instantly reverse the loop direction.

      The 2nd method: Tie an Aux switch to the Expression Pedal mapping. Personal preference, but with some advantages.  Below, the EXP PED mapping is shown Full Toe / Aux ON, triggering reverse playback.

      One major difference to note:  The Tensor will replace the loop, but the loop length will shrink or expand; depending on the time between HOLD switch taps.  The H9 Looper is replacing the loop, but dubbing to the full buffer length of 5.8 seconds.  If you stop playing, the Looper will REPL-LATCH with silence.

      One major advantage to note:  The H9 / TimeFactor loop can be dubbed in forward, reverse, or combinations of the two within the same loop.  Use the Aux switch mapping to Expression Pedal (or a rapid sweep with an expression pedal) to shift direction (PLAYSPEED), while you REPL-LATCH over the initial loop recording.  That, in addition to instant wind / rewind, at any point in the loop playback.

      For completeness, here would be one way to set up standard phrase looping in the Red Panda Tensor.  Again, the total loop length here is locked in, between latches of the HOLD switch.  Tap it once for a full-length of 5.8 seconds, and infinite, automatic playback in a forward direction.

       

      Now, for the best way to emulate that variable record buffer, you really need external control over the Record, Play, Clear … maybe Stop.  A number of individual Aux switches, or MIDI CC control, is going to make life easier.  In this configuration, direct control over Play can ‘stutter’ the phrase, by restarting the record buffer from the start point.  Here’s a description of the general idea:

      Take the ‘standard’ phrase loop configuration in the Red Panda Tensor, from the post above.  Loopers and standard delays can be set up in a similar way, but the internal routings are subtly different.  One Looper-style advantage lies in the ways the recorded material can be manipulated.

       

      A delay line feeds back into itself.  Loop manipulation can include FX that are inserted within that routing.  The FilterPong algorithm in the H9 / TimeFactor runs DELAY A in series with DELAY B.  In this preset, I split overall delay length between the two.  (I know, I know:  The math taken straight from the Tensor manual bothers me, too.  I’m guessing some kind of typo there, or 1-second processing diversion.)

      • Aux OFF – EXP PED HEEL  FEEDBACK  95
      • Aux OFF – EXP PED HEEL  MOD DEPTH  0
      • Aux OFF – EXP PED HEEL  FILTER  0
      • Aux ON  – EXP PED TOE    FEEDBACK  0
      • Aux ON  – EXP PED TOE    MOD DEPTH  5
      • Aux ON  – EXP PED TOE    FILTER  100

      With delay line regeneration, there has to be some way to ‘shut it off’; erase or edit the looping contents.  Here, FEEDBACK is set to 95 (cuts down on static hiss buildups), then switched to 0.  The dual buffers will play out full length, then stop.  Switching in & out during that time will selectively slice into the recorded audio loop.

      The FILTER effect is placed before the DELAY lines, so the filter effects are imprinted on the looping audio.  Those effects fade out with the final loop playback, or can be brought in & out of the loop with rapid switching or expression pedal sweeps.

       

      This FilterPong variation loses the filter effects, and replaces it with shifts to the audible delay buffers.

      • Aux OFF – EXP PED HEEL  DELAY MIX  A0+B10
      • Aux OFF – EXP PED HEEL  FEEDBACK  95
      • Aux ON  – EXP PED TOE    DELAY MIX  A10+B10
      • Aux ON  – EXP PED TOE    FEEDBACK  0

      An Aux switch or expression pedal layers DELAY A over DELAY B, and cuts the apparent length of the loop in half.  Pressing the REPEAT switch (bound to another Aux switch, or similar) recycles DELAY B only in an infinite loop (with dry on top).  Also half the apparent total length of the combined buffers.  This FILTERPONG preset has the potential for live manipulation of three distinct ‘loops’, with varying lengths and audible content.

      I just got around to trying these and — as always — they’re fantastic. Thanks Brock! I love trying out your presets. Even when one isn’t for me, I learn something new about the algorithm it uses.

        Thanks, mistercharlie.  I have a handful more presets to add here – OVR, sample-and-hold type effects, cool ADT doubling …  That incredible randomization knob:  It’s taking me two or three H9’s to even come close to the Tensor.  But all of this is actually forcing me to rethink the H9 algorithms, as well.

        I guess that’s my own 5.8 second typo above, that I kept re-referencing throughout this thread.  The actual Tensor buffer is about 4.8 seconds in length.  That makes all of these presets faithful to the original, the Tensor manual & math correct, and my uneditable prose above … unfaithful.

      I cannot wait to try these.
      Love my tensor but if the H9 could reproduce something like it, that would be great.
      Thanks for sharing.

        Let me know if there’s anything specific that you have in mind.   I have a few finished presets that I never uploaded, and many more in progress.  The randomization parameter is tough to duplicate with a single H9.  Just be aware of my 5.8 second typos above (should be 4.8 second maximum delay time).
