Q: What kind of internal processor does XTOMP use?
A: At the core of XTOMP is the powerful Texas Instruments C67 series DSP (Digital Signal Processor), which natively supports 32bit fixed-point, 32bit single-precision floating-point, and 64bit double-precision floating-point arithmetic.
Q: What about XTOMP’s digital computation accuracy?
A: XTOMP utilizes a 24 bit A/D and D/A chip. Though XTOMP’s accuracy in processing the different effects varies from model to model, by employing 64 bit double-precision floating point, and even 128 bit (by connecting two 64 bits) processing, XTOMP can guarantee the highest possible calculation accuracy, resulting in a virtually undetectable difference from the original tone.
Q: How many models can be stored in the XTOMP?
A: XTOMP works with one model at a time, allowing you complete control over the “original” effect in stompbox form. You have also available “combo” models which contain one or more effects. If you want to change tones, other models are available to download via the XTOMP App. The XTOMP model library will soon have over 300 classic tones online, not to mention several new Hotone original design models.
Q: How is the XTOMP CDCM technology different from similar modeling systems?
A: Hotone’s new era XTOMP is the fruit of a decade of circuit modeling research and development and employs our very own Comprehensive Dynamic Circuit Modeling (CDCM) system. CDCM has constructed an extremely complex dynamic variation matrix, able to realistically express every detailed change that occurs during the operational process of actual circuitry. That is to say, as XTOMP is operating, the models at work within it are constantly changing rather than remaining fixed. This matrix will adjust its own modeling parameters and even framework based on the instrument input signal range, signal frequency, knob position, the instrument’s own impedance, and other variable parameters, all to achieve the closest possible characteristics of actual circuitry.
CDCM can also accurately model a specific aspect of a circuit, including slight variations between resistors or capacitors, in detailed description. This modeling technology is made possible by the powerful processing capability XTOMP boasts in its internal floating point DSP chip. The chip focuses all of its power into recreating the tone of a single effects model algorithm. This ensures the effects model gets all the processing power, and that’s why it sounds so realistic. Other modeling products rely on a single chip to process a number of algorithms in series, which weakens the calculation and processing resources that any given model actually receives, resulting in a lower degree of accuracy.
Q: Where do the original effects units that XTOMP models come from?
A: Since all of XTOMP’s modeling is based on actual circuitry, Hotone had to find the actual original units featured in the XTOMP model library. In order to capture the most meaningful tones, Hotone spent a great deal of resources in obtaining those classic effects which have long since disappeared from the market. We are also very grateful to those friends who lent their vintage effects to our modeling research. The model library is always open, and we hope that Hotone friends worldwide with antique original gear will reach out so we can add their priceless tool to the family.
Q: Can XTOMP model other digital gear?
A: The Hotone research team came out with a digital modeling technology based on “black box theory” (different from CDCM) as early as 2001. The answer to whether or not XTOMP will model digital equipment in the future depends on customer demand!
Q: Why is XTOMP set up so that Left I/O is True Bypass and Right I/O uses Buffer Bypass?
A: XTOMP’s Left channel supports Relay and True Bypass, as well as Digital Buffer Bypass. The Right channel supports Analog Buffer Bypass and Digital Buffer Bypass. We arranged the L/R bypass to give options to suit people with different tonal and tech preferences. All of the models operate brilliantly in every bypass scenario.
Q: Will Bluetooth download affect the XTOMP tone in any way?
A: Bluetooth perfectly transfers the model to the XTOMP unit, ensuring pure tone and flawless functionality. Hotone also designed XTOMP to keep the Bluetooth signal from interfering with other nearby frequencies.
Q: How many XTOMP units can be connected to Bluetooth at once?
A: In theory, as many as you like. All the device connections will appear in the XTOMP App. From there you can get the device information and independently manage each unit’s software/firmware updates, rename models, and so forth.
Q: How were you able to make XTOMP so thin?
A: Even as Hotone demanded excellence in XTOMP’s circuitry and digital capabilities, we also had a high standard for its structural and aesthetic design. This design process spanned eight months, and the team came up with some unorthodox methods to reach the product’s ID goals and structural demands. One of these can be seen in the kick switch, which is unlike switches used in most other stompboxes that take up all of the internal space below them as the switch peg goes down deep into the box. XTOMP features a Tact Switch, which operates according to lever theory and leaves the inner casing more room for essential circuitry. The XTOMP design process is a classic example of Hotone’ s drive to “challenge the limits of design,” a principle that can be seen featured in several of the company’s products, many of which have been granted design patents.
Q: With XTOMP so thin, won’t it flip around when I step on it?
A: XTOMP’s thin design makes its center of gravity very low, and Hotone designed it with specific attention to ergonomics. We also took various venue scenarios into consideration. From its inception, XTOMP has always been a stompbox; it is probably more “stompable” than most of the other pedals you’re using.
Q: XTOMP is a good looking pedal, but will it get busted with use?
A: While Hotone designed XTOMP to be a sharp-looking musical tool, we also made sure it would hold up and keep looking great for years of use. XTOMP’s zinc alloy casing is extremely solid.
Q: What do the lights under the XTOMP knobs do?
A: With vintage equipment, the number of adjustment knobs obviously varies from pedal to pedal. That’s why XTOMP is fitted with multicolored lights underneath the knobs that show which knobs are for use as the unit “becomes” the stompbox it is modeling. Of course, these lights also make settings easy to see and are super cool looking on a dark stage.
For some models, the lights indicate the status of a knob setting. For example, if the original equipment had a toggle switch, that function will transfer to the XTOMP and be controllable in knob form. You can set up a color code in the App to show, for example, Boost ON/OFF. Set a knob light to change from say red (OFF) to green (ON), as you turn it and adjust your settings.
Q: Do I have to have a smart phone for the XTOMP to work?
A: Even though pretty much everybody has a smart phone, XTOMP is also equipped with a USB port for model updates. Hotone also has plans to add computer Bluetooth connectivity in the near future.
Q: Do I have to purchase XTOMP models?
A: The XTOMP model basic set is free.
Q: What model sets are there other than the basic set?
A: Hotone is compiling new model sets as the audio engineers continue to analyze, test, and compare more and more equipment. Remember, XTOMP can be almost anything!
Q: When will XTOMP hit the market?
A: The official launch will be on April 25th, 2016 and will start to hit the stores on May. Reserve yours soon!
