PanDualay Stereo Panning Delay (AUv3) PanDualay is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic or GarageBand. Overview PanDualay is an analog-flavoured stereo delay wih a variable left / right delay time ratio. In addition to stereo modulation and a LPF, PanDualay has an independent auto-pan that's applied to the delayed repeats only, giving an additional sense of stereo movement. PanDualy works especially well on lead / mono synth type sounds and can get pretty spacey! Parameters Active - Toggles the effect On or Off. Note that when you set the effect to Off, you will still hear the delay repeats, but your input signal is no longer fed into the delay processing. This is a similar idea to the "trails" feature in many delay effects units and pedals. Delay - Sets the base delay time between 50ms and 2 seconds. Regen - Sets the regeneration or feedback of the delay repeats up to 100% "endless" repeats. Note that at high Regen levels, the sound will appear to degrade in quality and become "washed-out" or "murky". This is intentional, and an attempt to capture the sound of analog delays with limited fidelity. Compression and limiting are also applied internally to prevent excessive build-up, which can also result in a "crunchy" sound at extreme settings as the repeats are squashed each time they're layered on top of each other. Again, this tends to be a sonic characteristic of analog and tape-based delays. Ratio - Sets a delay time multiplier for the left / right channels between 1 and 2. For example, a base Delay time of 500ms and a ratio of 1.5 : 1, will result in the left channel being delayed by 750ms and the right channel by 500ms. Interesting effects can be achieved by using non-standard ratios. For example, 1.62 is approximately the Golden Ratio, and at high Regen values can produce an almost reverb-like sonic wash! Pan - Sets the frequency of the auto-pan LFO. Note for the effect to be more obvious, the Ratio should be set to something other than 1 : 1. Mod - Applies a variable amount of stereo modulation to the delayed sound. LPF - Sets the cutoff frequency of a lowpass filter applied to the delay repeats. Reduce the LPF control for a darker echo sound. Mix - Sets the level of the delayed signal. Please note the dry / input signal is always present. If the name sounds familiar, PanDualay is an improved version of the PANDUALAY module developed for Voltage Modular by Waverley Instruments.

TETSUO is a chaotic percussion machine. No samples, no library. One voice built out of a pitched body with noise dragged through it, a resonant filter that saturates the harder you lean on it, a bitcrusher, and a waveshaper that runs from a bit of weight to total structural failure. The sequencer is sixteen unseen slots and STEPS knob decides how many of them fire, adding and taking away hits one at a time in a fixed order, so you can strip a pattern to the bone and build it back and the same beats come home. The SKIP control works against you on purpose, stealing hits at random while it plays, so it never quite settles. MUTATE modulates the pitch at random, setting fire to voices on every turn. You do not program TETSUO so much as negotiate with it. The strip along the top is how you attempt to hold onto anything. Sixty four steps, four turns of pattern, carved into as many as eight sections. Select a section. Find a sound. Hit RECORD, and that section keeps every knob position. Change it, record the next, then hit PLAY and it walks left to right dropping each snapshot in as it reaches it, looping. Drag the dividers to give a section longer or cut it short. It keeps settings, not audio, so the engine is playing live the entire way through. Sections save with your presets and your session. AUv3 and standalone.

Verdict
The clearest difference is price: PanDualay at $1.99 against TETSUO's $9.99. PanDualay also leads on ratings volume (5 vs 1) and iOS requirement (12.0 vs 15.6). On rating, review sentiment, ads and in-app purchases there is nothing between them.

PanDualay costs $1.99 and TETSUO $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 5.0 for PanDualay against 5.0 for TETSUO. That said, the two scores are not equally well evidenced: PanDualay has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
